Mon May 11 15:11:11 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

	* ace/OS.cpp (ctime_r): Renamed the fmtstr to
 	  ACE_OS_CTIME_R_FMTSTR for we may need to use similar scheme to
 	  fix other bugs in the future.

Mon May 11 14:50:47 CDT 1998  Everett Anderson  <eea1@cs.wustl.edu>

	* ace/Name_Proxy.cpp: Changed one last recv to recv_n.

Mon May 11 13:14:22 1998  Chris Gill  <cdgill@cs.wustl.edu>

        * ace/RB_Tree.{cpp,h,i}: (new) Red-Black Tree data structure
          implementation.  A Red-Black Tree is an efficient
          self-balancing binary tree that uses recoloring to
          minimize rotations while rebalancing on insertion or
          deletion of a tree node.  Items in the tree are stored
          according to a key provided at insertion.  This
          implementation is an OO rendition of the ADT described
          in Cormen, Leiserson, Rivest, "Introduction to Algorithms"
          (c) 1990, MIT.

Mon May 11 12:31:41 1998  Steve Huston  <shuston@riverace.com>

        * ace/OS.h: Made ACE_LD_SEARCH_PATH, ACE_LD_SEARCH_PATH_SEPARATOR_STR,
          ACE_DLL_PREFIX, ACE_DLL_SUFFIX settable via config.h.

        * ace/config-hpux-10.x.h:
          ace/config-hpux11.h: Set ACE_LD_SEARCH_PATH, ACE_DLL_SUFFIX.
          Thanks to Kirill Rybaltchenko and David Levine for identifying
          this problem.

Mon May 11 12:27:05 1998  David L. Levine  <levine@cs.wustl.edu>

        * ace/ACE.cpp (send_n): retry if ACE::send () fails due to
          EWOULDBLOCK.  Thanks to Dave Brackman <dbrackma@OhioEE.com>
          for reporting this.

        * tests/Env_Value_Test.cpp (main): check return values of
          options.setenv () calls.  Thanks to Bob Laferriere
          <laferrie@gsao.med.ge.com> for recommending this.

        * include/makeinclude/platform_vxworks5.x_ghs.GNU: instead of
          using GNU ranlib386 after using GHS ax for i386 targets, just
          use GNU ar386.

        * ace/gethrtime.cpp: added some comments about GHS asm support.

Mon May 11 05:14:18 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/config-WinCE.h: Added ACE_HAS_NON_STATIC_OBJECT_MANAGER.  CE
          console programs have to set this flag because the main
          functions is actually renamed and running in a threads.

        * tests/test_config.h: Excluded class and macros to redirect
          debugging messages to files under CE.  This make debugging a bit
          easier but we should eventually put them back under CE.

        * tests/Map_Manager_Test.cpp: Made CE friendly.

        * ace/Hash_Map_Manager.cpp: Some ACE_ERROR were not CE friendly.

        * ace/Profile_Timer.{h,i}:
        * ace/Synch.{h,i}: Moved inline function definitions to Synch.i
          file.  Windows CE can't grok any inline at all.

Mon May 11 02:43:45 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * performance-tests/Misc/childbirth_time.cpp (main): Added
          a new method for benchmarking ACE_Thread_Manager::spawn_n.
          Added other cosmetic changes.

Sun May 10 23:28:57 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/OS.cpp(inherit_log_msg):
        * ace/Log_Msg.cpp (thr_desc): Wait on Thread_Descriptor's lock
          instead of the "global" Thread_Manager lock.

        * ace/Thread_Manager.cpp: Moved acquire_release() from
          ACE_Thread_Manager to ACE_Thread_Descriptor.  This method is
          called from ACE_Log_Msg::thr_desc to prevent a thread from using
          its thread descriptor before it is fully built.  The change
          relieve spwaned threads from waiting for other threads created
          in the same spwan_n call to be created before it can start
          running.

          (insert): Added an extra argument to control whether we want to
          insert the newly created thread into ACE_Thread_Manager's thread
          table or not.  Notice that it is default to 1 to remain the
          original behavior in case anyone is using this class/function
          directly in their code.  However, in ACE_Thread_Manager, we
          always prevent it from inserting because we always register
          thread descriptors from spawn_i.

Sun May 10 01:51:29 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/OS.h: Renamed ACE_OS::Time_To_The_Beginning to
          ACE_OS::FILETIME_to_timval_skew.

        * ace/OS.cpp: Found the problem in ACE_OS::ctime_r.  An internal
          compiler bug (?) caused the bug.  The solution: move the format
          string out as a const string instead of putting it in sprintf
          directly.  Weird.

        * ace/Log_Record.{h,cpp}: Made priority_name_ and its access
          function CE friendly.

Sat May  9 20:09:13 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/Thread_Manager.h: Changed the type of lock used by
          <thread_desc_freelist_> to ACE_SYNCH_MUTEX.  Or else, it won't
          compile on platforms that doesn't support thread.  Thanks to
          Woody Zenfell <woody@arl.wustl.edu> for reporting this.

Fri May 08 22:29:01 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/SOCK_Dgram_Mcast.cpp (subscribe): CE UNICODE related fix.

Fri May  8 14:18:46 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/Thread_Manager.h (ACE_Thread_Descriptor): Added ACE_INLINE
          to declarations of set_next and get_next to get around a bug in
          a version of g++.

Fri May  8 11:57:23 1998  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Map_Manager.cpp: Fixed a bug where we weren't calling
          close_i() when resizing the buffer.

        * ace/Thread_Manager.cpp (set_grp): In
          ACE_Thread_Manager::{get,set}_grp we must check to see that we
          have a valid pointer after the ACE_FIND.  Otherwise a seg fault
          occurs.  Thanks to Chris Lahey <CLahey@cccis.com> for reporting
          this.

Fri May 08 09:47:50 1998  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-linux-common.h: only use ACE_HAS_POLL with glibc2.
          Thanks to Saneyasu <sane@sail.t.u-tokyo.ac.jp> for reporting
          this.

        * ace/OS.i (sleep): On Linux without ::poll () (prior to glibc),
          copy the ACE_Time_Value argument because the system modifies it.

        * include/makeinclude/platform_osf1_4.0.GNU: moved -lm from LIBS
          to MATHLIB.

        * performance-tests/UDP/Makefile: added $(MATHLIB) to LDLIBS.

        * tests/Aio_Platform_Test.cpp (have_asynchio): use
          _SC_LISTIO_AIO_MAX instead of _SC_AIO_LISTIO_MAX if it's
          #defined.  It is on DU 4.0.

Fri May 08 08:43:42 1998  Steve Huston  <shuston@riverace.com>

        * include/makeinclude/platform_hpux_gcc.GNU: Added $(PIC) to
          definition of SOFLAGS.  Thanks to Kirill Rybaltchenko
          <Kirill.Rybaltchenko@cern.ch> for this fix.

        * ace/SOCK_Dgram_Mcast.cpp (subscribe): Added code for Win32 so that
          if a subscribe is done without specifying an interface, the mcast
          address is subscribed to on each non-loopback interface.  This works
          around a bug in NT's winsock in the presence of multiple IP
          interfaces.  Won't hurt 95 - will just run a bit slower than it
          otherwise would.

        * examples/Reactor/Multicast/Multicast.{mdp,mak}: Added MSVC 4.2
          workspace for this example.

Fri May  8 03:43:25 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/Thread_Manager.{h,cpp}: Added yet one more member variable
          into Thread_Descriptor to keep track of registration of
          Thread_Descriptors.  By adding this variable, we can avoid an
          extra locking in remove_thr for most cases (normal cases ;-).
          Thanks to the inspiration from Arturo Montes
          <mitosys@colomsat.net.co>.

Wed May 06 18:35:21 1998  Steve Huston  <shuston@riverace.com>

        * ace/ACE.cpp (get_ip_interfaces): Reset buf_len before each call to
          get_reg_key to get registry value for device's IP address.  It gets
          overwritten on each call to get_reg_key.

        * include/makeinclude/platform_mvs.GNU: Added definition for PIC.
          Though not related to position-independent-code, it is a switch that
          makes shared lib builds work right.  Removed the old SOBUILD def.
          Thanks to Chuck Gehr for helping with this strategy.

Thu May 07 22:06:13 1998  Ben Eng  <ben@jetpen.com>

        * ace/config-kcc-common.h,config-linux-{common,kcc}.h: updated
          KCC/Linux support, and integrated into config-linux-common.h.

Thu May  7 20:32:20 1998  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * examples/Service_Configurator/IPC-tests/client/local_dgram_client_test.cpp
          (main): Oops, we need to move the unlink() AFTER we create the
          file...  Thanks to Sandro Doro <doros@aureus.sublink.org> for
          reporting this.

Wed May  6 02:57:40 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/Filecache.h (ACE_Filecache_Handle): Removed
          ACE_EXPORT_DECLARE and specified ACE_Export directly for
          ACE_Filecache_Handle and ACE_Filecache in calss declarations.

        * ace/Thread_Manager.{h,i,cpp}: A bug was found by Arturo Montes
          <mitosys@colomsat.net.co> who noticed that when a thread was
          spawned and then exited immediately, its thread descriptor might
          get freed before even get registered into the thread table kept
          by the Thread_Manager.  Although it doesn't make any sense to
          spawn a thread just to let it return immediately, a middleware
          shouldn't restrict the way how users want to use it.

          I got around this problem by adding a lock into
          Thread_Descriptor.  Before spawning a thread, the Thread Manager
          will first grab the lock.  It won't release the lock until
          calling append thread, at which point, the Thread_Descriptor of
          the thread has been stashed into the table.  Removing the
          Thread_Descriptor also requires to hold this lock and release
          the lock before the Thread_Descriptor is "freed."  Therefore,
          if a thread exit before its Thread_Manager ever gets a chance to
          register it, it will block and waiting.

          The type of the lock is defined by ACE_DEFAULT_THREAD_MANAGER_LOCK
          which, by default, is ACE_Thread_Mutex.  User can change the
          definition by defining in their config.h file.  For example, if
          you can be sure that all your threads will run for an extended
          long time (which, in most case, should be true,) you can disable
          this feature by defining this as a ACE_Null_Mutex to speed up
          spawning and termination of threads.

          (thread_desc_freelist_): Added a free list to Thread_Manager to
          recycle Thread_Descriptor.  By default, this free list
          pre-allocate 0 Thread_Descriptor and has low-water-mark of 1,
          increment count 1 and a huge (25000) high water mark.  That is,
          if you use a Thread_Manager for an extended period of time, you
          won't have to dynamically allocate memory for Thread_Descriptor
          for every thread after your system is stable (the thread count
          fluctuates between some certain values.)

          There are two ways to change the settings.  First, by defining
          ACE_DEFAULT_THREAD_MANAGER_LWM, ACE_DEFAULT_THREAD_MANAGER_HWM,
          ACE_DEFAULT_THREAD_MANAGER_INC, and
          ACE_DEFAULT_THREAD_MANAGER_PREALLOC in your <config.h> file.
          This changes the default setting of your ACE.  (The global
          Thread_Manager use this setting.)  Or, you can specify these
          values when creating a Thread_Manager.

        * ace/Free_List.cpp (alloc,dealloc): Don't grab the lock in these
          two functions.  They only get called from add() and remove()
          which hold the lock before making the call.  Actually, they also
          gets called from the constructor and destructor.  But that
          shouldn't be a problem.

        * tests/Reactor_Notify_Test.cpp (run_test): Moved the #endif of
          ACE_HAS_THREADS down to avoid compilation error on non-threaded
          platforms.

Thu May 07 19:08:22 1998  Douglas C. Schmidt  <schmidt@cs.wustl.edu>

        * ACE version 4.5.2 released.

Thu May  7 14:10:41 1998  Carlos O'Ryan  <coryan@cs.wustl.edu>

        * ace/Timer_Hash_T.h:
        * ace/Timer_Hash_T.cpp:
        * ace/Timer_Heap_T.cpp:
        * ace/Timer_Wheel_T.cpp:
          The classes had a INHERITED typedef for the base class, but
          Solaris defines a macro by the same name. This causes very weird
          problems with EGCS (and probably other g++ versions).

Thu May 07 04:15:23 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/Profile_Timer.cpp (elapsed_time): Treat Win32 differently
          so I can use this function with WinCE Emulation build.  The
          problem is that Win32 can't convert __int64 to double.

        * ace/OS.{h,cpp} (ACE_Time_Value): (Win32 only) Added a new static
          const member (Time_To_The_Beginning) of type DWORDLONG (unsigned
          _int64) to adjust the time skew between FILETIME and POSIX time.
          Changed the type of _100ns to ULARGE_INTEGER to eliminate
          unnecessary computation.

Wed May  6 23:58:40 1998  Carlos O'Ryan  <coryan@swarm.cs.wustl.edu>

        * ace/XtReactor.cpp:
          The signature for the open() method of the notify pipe has been
          modified.

Wed May  6 23:28:47 1998  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * examples/Service_Configurator/IPC-tests/client/local_dgram_client_test.cpp:
          Fixed a couple of mistakes that were causing the UNIX domain
          sockets not to work.  Thanks to Sandro Doro
          <doros@aureus.sublink.org> for recommending this.

        * performance-tests/Misc/context_switch_time.cpp (svc): An 'i'
          was being defined twice, gorp!  It's fixed now!

Wed May 06 22:00:14 1998  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-linux-common.h: only #define
          ACE_HAS_4_4BSD_SENDMSG_RECVMSG with __GLIBC__.  Thanks
          to Chanaka Liyanaarachchi <chanakal@ittc.ukans.edu> for
          reporting the lack of CMSG_DATA support on RedHat 4.2.

Wed May 06 18:35:21 1998  Steve Huston  <shuston@riverace.com>

        * ace/ACE.cpp (get_ip_interfaces): Reset buf_len before each call to
          get_reg_key to get registry value for device's IP address.  It gets
          overwritten on each call to get_reg_key.

        * include/makeinclude/platform_mvs.GNU: Added definition for PIC.
          Though not related to position-independent-code, it is a switch that
          makes shared lib builds work right.  Removed the old SOBUILD def.
          Thanks to Chuck Gehr for helping with this strategy.

Wed May 06 16:32:53 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/Filecache.h (ACE_Filecache_Handle): Removed
          ACE_EXPORT_DECLARE and specified ACE_Export directly for
          ACE_Filecache_Handle and ACE_Filecache in calss declarations.

        * ace/Thread_Manager.{h,i,cpp}: A bug was found by Arturo Montes
          <mitosys@colomsat.net.co> who noticed that when a thread was
          spawned and then exited immediately, its thread descriptor might
          get freed before even get registered into the thread table kept
          by the Thread_Manager.  Although it doesn't make any sense to
          spawn a thread just to let it return immediately, a middleware
          shouldn't restrict the way how users want to use it.

          I got around this problem by adding a lock into
          Thread_Descriptor.  Before spawning a thread, the Thread Manager
          will first grab the lock.  It won't release the lock until
          calling append thread, at which point, the Thread_Descriptor of
          the thread has been stashed into the table.  Removing the
          Thread_Descriptor also requires to hold this lock and release
          the lock before the Thread_Descriptor is "freed."  Therefore,
          if a thread exit before its Thread_Manager ever gets a chance to
          register it, it will block and waiting.

          The type of the lock is defined by ACE_DEFAULT_THREAD_MANAGER_LOCK
          which, by default, is ACE_Thread_Mutex.  User can change the
          definition by defining in their config.h file.  For example, if
          you can be sure that all your threads will run for an extended
          long time (which, in most case, should be true,) you can disable
          this feature by defining this as a ACE_Null_Mutex to speed up
          spawning and termination of threads.

          (thread_desc_freelist_): Added a free list to Thread_Manager to
          recycle Thread_Descriptor.  By default, this free list
          pre-allocate 0 Thread_Descriptor and has low-water-mark of 1,
          increment count 1 and a huge (25000) high water mark.  That is,
          if you use a Thread_Manager for an extended period of time, you
          won't have to dynamically allocate memory for Thread_Descriptor
          for every thread after your system is stable (the thread count
          fluctuates between some certain values.)

          There are two ways to change the settings.  First, by defining
          ACE_DEFAULT_THREAD_MANAGER_LWM, ACE_DEFAULT_THREAD_MANAGER_HWM,
          ACE_DEFAULT_THREAD_MANAGER_INC, and
          ACE_DEFAULT_THREAD_MANAGER_PREALLOC in your <config.h> file.
          This changes the default setting of your ACE.  (The global
          Thread_Manager use this setting.)  Or, you can specify these
          values when creating a Thread_Manager.

        * ace/Free_List.cpp (alloc,dealloc): Don't grab the lock in these
          two functions.  They only get called from add() and remove()
          which hold the lock before making the call.  Actually, they also
          gets called from the constructor and destructor.  But that
          shouldn't be a problem.

        * tests/Reactor_Notify_Test.cpp (run_test): Moved the #endif of
          ACE_HAS_THREADS down to avoid compilation error on non-threaded
          platforms.

Tue May  5 14:12:08 1998  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * include/makeinclude/platform_sco5.0.0-fsu-pthread.GNU: Added a
          platform config file courtesy of Arturo Montes
          <mitosys@colomsat.net.co>.

Tue May 05 08:35:18 1998  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-irix6.x-sgic++-nothreads.h: updated the determination
          of ACE_SIZEOF_LONG_DOUBLE.  Thanks to Bob Laferriere
          <laferrie@gsao.med.ge.com> for providing the fix.

        * include/makeinclude/platform_sunos5_g++.GNU: use -gstabs+ instead
          of -g on Solaris86.

        * etc/Svc_Conf_l.cpp.diff: updated.  It's magic, Nanbor :-)
          The problem seems to be due to an old version left in
          /tmp/Svc_Conf_l.cpp, which confuses flex.

        * ace/config-linux-common.h,config-g++-common.h: moved
          ACE_HAS_PENTIUM (with i386) from config-linux-common.h
          to config-g++-common.h.

        * ace/config-linux-common.h: added ACE_HAS_POLL, so we
          don't use ::select () in ACE_OS::sleep ().  Linux's
          ::select () modifies its timeout argument!

        * ace/OS.i (gethrtime): added RDTSC support for all g++
          _and_ ACE_HAS_PENTIUM platforms.

        * ace/config-vxworks5.x.h: added ACE_HAS_PENTIUM with GHS
          on Intel platforms.

        * ace/Makefile: for GHS on Intel 8086, build gethrtime.cpp.
          It's used to provide a high-resolution time using the
          Pentium RDTSC instruction.  I don't know how to get
          GHS' asm to do it, so it uses g++.

        * ACE-INSTALL.html: added note about carefully installing
          egcs on Linux.  Thanks to Kurt Sussman <kls@best.com> for
          tracking down the cause of mysterious link failures.

Tue May 05 02:15:49 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/Svc_Conf_l.cpp: I know, I know.  I shouldn't mess with this
          file directly.  But I couldn't manufacture this file even with
          the stock Svc_Conf.l using Doug's flex.  So, I reckon I'll just
          check this in now and fix the Svc_Conf_l.diff later.

        * ace/Service_Config.{h,cpp} (process_directive): Standard CE
          stuff.

        * WindozeCE/WinAdapter*.*:
        * WindozeCE/WindozeCE*.*: Replaced the old adapter for CE with a
          new one.  The new version allows uses to scroll thru the
          "console" output.

Mon May 04 17:09:39 1998  David L. Levine  <levine@cs.wustl.edu>

        * performance-tests/Misc/context_switch_time.cpp: lots of
          cleanup.  The main changes were the use of ACE_THR_PRI_FIFO_DEF
          for the default therad priority, and removal of some
          unnecessary thr_yield () calls.

        * tests/Aio_Platform_Test.cpp: added arguments to main (),
          removed #includes that are already in ace/OS.h, and added
          ACE_START_TEST/ACE_END_TEST calls.

Mon May  4 13:08:18 1998  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/config-sunos5.6.h: Removed a mysterious "30" at the end of
          an #undef.  Thanks to J. Russell Noseworthy
          <rnosewor@objectsciences.com> for reporting this problem.

Mon May 04 08:49:09 1998  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.cpp (ACE_Thread_Adapter::invoke): with ACE_NEEDS_LWP_PRIO_SET,
          added the call to ACE_OS::thr_setprio () so that the LWP priority
          will be set if running in the RT class.  Applications no longer
          have to be concerned with this.

        * performance-tests/Misc/preempt.cpp (svc): removed
          ACE_OS::thr_setprio () calls to set LWP priority, now that ACE
          handles that internally.

        * include/makeinclude/platform_*linux.GNU: added "s" to
          ARFLAGS, so that ranlib is no longer necessary.

Sun May 03 22:37:38 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/Parse_Node.cpp (open_handle): WinCE doesn't support
          ExpandEnvironmentStringA.

        * ace/config-win32-common.h: Only define ACE_HAS_GETRUSAGE when
          ACE_HAS_WINNT4 != 0.  Thanks to Paul Motuzenko
          <p_motuzenko@hotmail.com> for reporting this.

Sun May 03 01:58:47 1998  Douglas C. Schmidt  <schmidt@cs.wustl.edu>

        * ACE version 4.5.1 released.

Sat May  2 14:35:04 1998  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * tests/Reactor_Notify_Test.cpp: Factored out some common code to
          make the test more concise.

        * tests/Reactor_Notify_Test.cpp: Modified the test to check
          whether our new mechanism for disabling the notify pipe works
          correctly.

        * ace/{WFMO,Select}_Reactor[_Impl]: Added the
          "disable_notify_pipe" flag in the constructor in order to
          disable this feature and save on descriptors if they aren't
          required.  Thanks to Tom Venturella <tventurell@mdc.com> for
          motivating this.

Sat May 02  Alexander Babu Arulanthu  <alex@merengue.cs.wustl.edu>

        * tests/Aio_Platform_Test.cpp: Included this test program for
        testing a platform for Asynchronous I/O options.
        * tests/Makefile (BIN): Added Aio_Platform_Test.

Fri May 01 17:52:32 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/Arg_Shifter.{h,cpp}: Added macros ACE_Export and
          ACE_BUILD_DLL respectively.

        * ace/ACE_Library.mak:
        * ace/ace_{dll,lib}.dsp: Added Arg_Shifter.cpp into project.

Fri May  1 13:52:32 1998  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Addr: Made the destructor for ACE_Addr virtual so that
          subclasses can be deleted correctly.  Thanks to Wei Chiang
          <chiang@horizon.ntc.nokia.com> for reporting this.

        * ace: Added Arg_Shifter from TAO and renamed it to
          ACE_Arg_Shifter.

        * ace/IOStream_T.i (recv_n): ACE_IOStream<STREAM>::eof (void) had
          a subtle bug if it is called when a get operation (>>) has not
          failed.  Thanks to James CE Johnson <ace-users@lads.com> for
          reporting this bug.

        * examples/Connection/misc/Connection_Handler.cpp: Make sure to
          activate() each active object using THR_DETACHED so we don't run
          out of threading resources.  Thanks to Brad Walton
          <brad.walton@transnexus.com> for reporting this.

        * ace/Timer_Queue_Adapters.cpp: Rather than returning the result
          of schedule_ualarm(), the
          ACE_Async_Timer_Queue_Adapter<TQ>::schedule() method should
          return the timer id.  Thanks to James Garrison
          <jhg@austx.tandem.com> for reporting this.

        * examples/System_V_IPC/SV_Message_Queues: Renamed the so-called
          "ACE_Message_Block" to "Message_Block" so it wouldn't be as
          confusing.  Thanks to Ganapathi <guns@fs.IConNet.NET> for this
          suggestion.

Fri May 01 17:52:32 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/ACE_Library.mak:
        * ace/ace_{dll,lib}.dsp: Added Arg_Shifter.cpp into project.

Fri May 01 14:09:21 1998  Steve Huston  <shuston@riverace.com>

        * ace/OS.h: Changed ACE_hrtime_t from signed to unsigned on Win32
          to insure correct results from ACE_High_Res_Timer::elapsed_time
          calculations.  Fixes bug P87.

Fri May 01 11:52:47 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * ace/OS.h: Forgot to redefine ASYS_INLINE after #undef it.

        * ace/OS.i (last_error): On Win32, this should also update errno
          after calling SetLastError ().  Thanks to Steve for pointing
          this out.  Fixes bug P88.

Fri May 01 10:01:09 1998  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-sunos5.6.h: replaced config-sunos5.6-sunc++-4.x.h
          with this config file, which supports both Sun C++ and g++.

        * ace/OS.i (gethrtime): for the default (::gettimeofday) case,
          use 64-bit instead of 32-bit arithmetic by casting to ACE_hrtime_t.

        * ace/Basic_Types.{h,i}: added ACE_U_LongLong::operator *.

        * ace/Env_Value_T.cpp: added #include of Env_Value_T.h.

Fri May  1 00:35:40 1998  Nanbor Wang  <nanbor@cs.wustl.edu>

        * include/makeinclude/wrapper_macros.GNU
          (ACE_LDSO_Version_Number): Fixed the problem of not able to
          parse a formal release number from ace/VERSION.

        * ace/config-WinCE.h: Added ACE_LACKS_INLINE_FUNCTIONS.

        * ace/OS.h: Added a new macro ASYS_INLINE for platforms that don't
          support inline properly.  This is controlled by the macro
          ACE_LACKS_INLINE_FUNCTIONS.

          Walked thru all macros and indented them properly.

        * ace/README: Added documentation for ACE_LACKS_INLINE_FUNCTIONS.
