 ----------------
+Version 5.003_05
+----------------
+
+This patch was primarily to fix bugs and to clean up some of
+the remaining issues from in 5.003_04.  The details are described below.
+A very brief summary is:
+
+o Visible Changes to Core Functionality
+
+   -Add support for a READLINE method to tied filehandles.
+    
+   -times function now uses CLK_TCK if HZ is not available, rather
+    than just defaulting to 60.  times output might change on some
+    systems, but should be correct now.
+
+   -AnyDBM_File (modifying ISA does not work as expected)
+    Now behaves as documented:  Modifying ISA works to select
+    order in which *DB* modules are tried.  The default is still
+    the same.
+
+o Configure and build enhancements
+
+   -Enhance detection of [gs]etpgrp() variants.  Some systems have
+    BSD-style behavior for one and POSIX for the other.  Use
+    [gs]etpgid() instead, whenever possible.
+  
+   -You can now build a shared libperl.so without running through
+    the LD_RUN_PATH hoops, if your system supports appropriate
+    ld command-line options.  Solaris, NetBSD, and Linux are currently
+    supported.  Others are easy to add.  (This makes like a lot easier
+    for embedders.)
+
+   -VMS updates.
+    
+   -Fix installperl and installman so that the -n option really only
+    prints commands.  (previously, it would still do the mkdirs.)
+
+o Bug fixes
+
+   -debugger ought to work.
+
+   -A new heredoc tag in Makefile.SH is now quoted.  This prevented
+    5.003_04 from working most places.
+
+   -numerous smaller ones, detailed below.
+
+o Specific Changes
+
+Here are the specific file-by-file changes.
+
+# This is my patch perl5.003_05.pat to perl5.003_04
+# The full description is below.
+# Please execute the following commands before applying this patch.
+# (You can feed this patch to 'sh' to do so.)

+# executable.

+
+This is patch perl5.003_05.pat to perl version 5.003_04.
+This takes you from 5.003_04 to 5.003_05.
+
+To apply this patch, run the above commands,
+cd to your perl source directory and then type
+
+	patch -p1 -N < perl5.003_05.pat
+
+The changes are described after each /^Index/ line below.  This is
+designed so you can examine each change with a command such as
+
+	csplit -k perl5.003_05.pat '/^Index:/' '{99}'

+Index: Changes
+
+    Updated for 5.003_05.
+
+Index: Configure
+
+    Allow command line or hint-file overrides of $afs.
+
+    Allow trailing spaces in nm output for HPUX10.
+
+    Check for newer BIND 'search' directives in /etc/resolv.conf as well
+    as older 'domain' directive.
+
+    Enhance detection of [gs]etpgrp() variants.  Some systems have
+    BSD-style behavior for one and POSIX for the other.  Use
+    [gs]etpgid() instead, whenever possible.
+
+    Include -s in the -h summary of available options.
+
+    Allow command-line override of $afs.
+
+    Handle trailing spaces in nm-output on HPUX10.
+
+    Set shrpenv for handling LD_RUN_PATH, if needed. (This used to
+    be in Makefile.SH.  Now it's available for other modules too.)
+
+    When using shared libperl, avoid LD_RUN_PATH if possible by adding
+    correct ld flags.  Currently, Solaris and NetBSD get the correct
+    -R $archlibexp/CORE, and Linux gets its
+    -Wl,-rpath,$archlibexp/CORE flag.  Other contributions are
+    welcome.

+
+    Subject: debugger problems--another patch (was Re: 5.003_04)
+
+    I have tried to avoid copying of hash keys that are passed to
+    magical hashes, but it seems that copying may be unavoidable
+    since the hv_*_ent() functions could be PADTMPs (and other
+    SVs that may get reused) as keys.

+    Now behaves as documented:  Modifying ISA works to select
+    order in which *DB* modules are tried.  The default is still
+    the same.
+
+
+    Add helpful "die" message to end of AnyDBM_File.  Previously
+    it would return a 0, and the failure would eventually show up
+    somewhere else in the script and be hard to track down.  It is
+    a failure if perl can't open AnyDBM_File.  The test regression
+    suite is supposed to indicate this as a failure too.

+Index: lib/File/Find.pm
+
+    From: Michael Mahan <mahanm@nextwork.rose-hulman.edu>
+    Subject: Cwd::fastcwd in File::Find
+
+    Is there a good reason why File::Find uses Cwd::fastcwd instead of
+    Cwd:cwd when fastcwd isn't as portable?
+    [In particular, fastcwd() doesn't work on AFS.]
+
+Index: lib/Math/Complex.pm
+
+    There was a mistake in the sqrt routine in lib/Math/Complex.pm that
+    gave wrong answers when the magnitude of the imaginary part of the
+    argument exceeded the magnitude of the real part.  Line 69 had too
+    many sqrt($y)'s.  Further, expressions were re-arranged so that
+    calls to the expensive real sqrt() routine were reduced from 4 to 2
+    in this case.
+
+Index: lib/open3.pl
+
+    The I/O directions on the dad_wtr and kid_rdr were backwards.
+    IO/Open3.pm didn't have this error.
+
+Index: lib/syslog.pl
+
+    Date: Tue, 03 Sep 1996 20:33:54 -0400
+    From: Roderick Schertler <roderick@gate.net>
+    Subject: syslog.pl `use Socket' lossage
+
+    syslog.pl tries but fails to use
+    Socket.pm, the problem is that use doesn't return a true value.  This
+    module should be recast in terms of Sys::Syslog, of course.
+
+Index: makedepend.SH
+
+    This patch eliminates "\|" in sed patterns in makedepend.SH, since
+    they're not really needed anyway in this one case.
+
+Index: mg.c
+
+    Ok, here's a tested patch for the debugger problem.
+    I was missing the fact that DB::dbline magic is actually
+    uppercase (which means hv_store_ent() etc., will pass SV keys
+    to the vtbl_dbline handlers).
+
+    Replace the oft-repeated mg_ptr incantation with
+    the simple MgPVKEY macro.
+
+    Rename MgPVKEY to MgPV (to match with HePV elsewhere).  Add
+    additional parens around the "mg".
+
+    (lines near 584) Part of VMS changes.  I don't know what this did.
+
+    Date: Fri, 23 Aug 1996 17:20:22 -0400 (EDT)
+    From: Chip Salzenberg <salzench@nielsenmedia.com>
+    Subject: Integerize mg.c; eliminate warning on C< local($)) >
+
+    This patch converts magic variables ($!, $^E, etc.) to use integers
+    (C<sv_setiv>) instead of floats.  It also eliminates a warning from
+    C< local($)) >, via a hack similar to $!.
+
+Index: mg.h
+
+    Replace the oft-repeated mg_ptr incantation with
+    the simple MgPVKEY macro.
+
+    Rename MgPVKEY to MgPV (to match with HePV elsewhere).  Add

+
+    Change to subversion 5.
+
+Index: perl.c
+
+    Make floating point constants Locale-friendly.
+
+Index: perl.h
+
+    One last LONG & co. fix (yet another cut'n'paste error) and a few

+
+    Enhance detection of [gs]etpgrp() variants.  Some systems have
+    BSD-style behavior for one and POSIX for the other.  Use
+    [gs]etpgid() instead, whenever possible.
+
+Index: perlio.c
+
+    Eliminate potential "signed vs. unsigned" warning
+
+    Add PerlIO_reopen and PerlIO_cgetname functions.
+
+Index: perlsdio.h
+
+    Don't supply redundant parameters for PerlIO_open and PerlIO_fdopen.
+
+    Include PerlIO_reopen and PerlIO_getname.
+
+    s/FILE_(CNT|PTR)_LVALUE/STDIO_(CNT|PTR)_LVALUE to fix a typo.
+    This had prevented SV_FAST_FGETS from working anywhere.
+
+    Include PerlIO_canset_cnt.  I'm not sure how this is supposed to
+    differ from STDIO_CNT_LVALUE.
+
+Index: pod/Makefile
+
+    Remove trailing spaces in pods.
+    Include a call to the checkpods script in the Makefile (though it's
+    not ordinarily used by users).
+
+Index: pod/checkpods.PL
+
+    New script to check for common errors in pods.  This is not

+
+    This patch provides minor speedups by using integer math and SVt_IV
+    values when performing bitwise operations and modulus.

+    just plain chsize if this system HAS_CHSIZE.  This probably only

+    From: Chip Salzenberg <salzench@nielsenmedia.com>
+    Subject: Minor potential bug in AV creation
+
+    I wasn't the one who originated this patch.  But it looks like it
+    would improve the safety of AV creation.
+
+    Remove potentially incorrect casts on PerlIO_set_ptrcnt.
+    'ptr' is already STDCHAR, which is supposed to be the type of

+    Subject: Perl 5.003.03: race condition in t/lib/io_sock.t
+
+    io_sock.t works by forking a subprocess it can communicate with.
+    It has the subprocess wait for the main process by sleeping 10
+    seconds or until an alarm arrives.
+
+    With my setup, the alarm signal arrives *before* the child
+    has a chance to ignore the alarm signal.
+
+    I fixed this by moving the "$SIG{ALRM} = sub {};" up before the
+    fork. It does not hurt to have the parent ignore alarms, too.
