+ * Makefile.in (LIB): Remove -lufc.
+ * config.h (RSH_NOT_TRANSPARENT): Define.
+ * Makefile.in: Use ${top_srcdir}/windows-NT/rcmd.* not our

+
+Tue Jun 17 13:19:53 1997 Jim Kingdon <kingdon@harvey.cyclic.com>
+
+ * README: Revise paragraph on -Zsys to discuss problem with
+ sockets being missing.
+
+Mon Jun 16 10:58:46 1997 Jim Kingdon <kingdon@harvey.cyclic.com>
+
+ * README: Change bug submission address to include bug-cvs.
+ Add paragraph (from the mail message of the submission) concerning
+ HPFS and such. Cosmetic changes (two spaces after periods for
+ example). Say that ufc-crypt shouldn't be needed currently.
+ Add comment about emx.dll.
+ * config.h, startserver.c, rcmd.h, rcmd.c, system.c: Add
+ "copyright" notice.
+ * system.c (os2_initialize): Add comment about whether we should
+ be expanding wildcards here. Cosmetic changes throughout
+ (for example, reindenting just about everything).
+ * system.c (xgetwd): Rewritten and renamed from os2_getwd.
+ * config.h (CVS_GETWD, os2_getwd): Removed.
+ * rcmd.c: Add comment about portable versus OS-specific
+ implementations of this functionality.
+ * config.h: Remove SIZEOF_INT, SIZEOF_LONG, HAVE_MKFIFO,
+ HAVE_SETVBUF, and USE_DIRECT_TCP; no longer used.
+ * config.h: Add USE_SETMODE_BINARY.
+ * config.h: Define NO_EXT_METHOD.
+ * Makefile.in (LIB_SOURCES): Remove lib/xgetwd.c; replaced by
+ xgetwd in system.c.
+ (LIB_OBJECTS): Likewise, remove lib/xgetwd.o.
+ * Makefile.in (DISTFILES): Add missing "/".
+ * .cvsignore: Added.
+
+ * New directory. This consists of the port that Thomas Epting
+ sent to bug-cvs on 18 Mar 97. He also sent some diffs which go
+ with this; I'll subsequently be checking in some of those diffs
+ and my various tweaks to the code.

+
+CVS for OS/2
+based on EMX 0.9c (patch 02)
+
+
+This port works well in local mode. It fully respects the OS/2
+filename conventions, but only works on HPFS or other filesystem types
+which support long filenames (like ext2fs or Netware FS with OS/2
+namespace). It does _not_ work on FAT partitions or any other fs which
+does not support long filenames. The port also works in client mode.
+
+This port requires EMX 0.9c (patch 02) and the BSD libraries. It should
+work in local mode, in client mode and also in server mode. nServer mode
+will only work if the client uses the :server: method, because the CRLF
+handling of IBM's RSHD.EXE is not "compatible" with CVS. (If you find a
+better rshd for OS/2, please let us know!)
+
+To compile CVS for OS/2, you must install the following packages:
+
+ - EMX 0.9c (patch 02) and the GNU-C-Compiler
+
+ EMXDEV1.ZIP
+ EMXDEV2.ZIP
+ EMXRT.ZIP
+ GNUDEV1.ZIP
+ GNUDEV2.ZIP
+ BSDDEV.ZIP
+ EMXFIX02.ZIP
+
+ - GNU make for OS/2
+
+ GNUMAKE.ZIP
+
+ - ufc.a (ufc-crypt) as a replacement for crypt (this may be something
+ different if you live inside the USA). You don't need this one currently,
+ because the port of the server to OS/2 isn't done yet, but I'm mentioning
+ in case it is useful for future reference (we're probably better off
+ using a different password hash instead, as noted in item #184 of ../TODO).
+
+ GNUUFC.ZIP
+
+All packages can be found on ftp://ftp.leo.org/pub/comp/os/os2/leo/gnu
+(You may also try http://www.leo.org/pub/comp/os/os2/leo/gnu).
+
+Change to the `emx' directory, do "make" and get emx\cvs.exe. I had
+to comment out the "Makefile" rule in emx/Makefile to avoid a
+complaint about ../config.status not existing. You also might need to
+edit srcdir to be "." and top_srcdir to be "..".
+
+Assuming you have edited the `install_dir' variable in the Makefile,
+you may type "make install-cvs" to put cvs.exe in the right place.
+You may also "make clean-cvs" to clean up object and library files.
+
+The cvs.exe generated will require emx.dll to run. You can try
+compiling with -Zomf -Zsys to generate a cvs.exe without this
+requirement, but that almost surely will require significant changes
+to make it work. For the client, the big known problem would be that
+EMX 0.9c doesn't have sockets with -Zsys (according to the
+documentation). That seems like it would be hard to get around. For
+local, the big known problem is that -Zsys doesn't have fork(). This
+one isn't as bad--using os2/run.c or something similar instead of
+src/run.c should solve this problem.
+
+You will get warnings in lib/getdate.c. These are yacc's fault; ignore
+them.
+
+You will get about 5 warnings in lib/regex.c concerning "unused variable
+destination". Ignore them.
+
+Report bugs to tepting@swol.de and bug-cvs@nongnu.org.
