This is GNU diff 1.15-ms, which is GNU diff 1.15 patched
for use on a PC running OS/2 1.x or MS-DOS 3.x and newer,
plus a few extra features that may appear in later releases
of GNU diff.
The following files contain changes from GNU diff 1.15:
analyze.c context.c diff.c diff.h diff3.c dir.c
getopt.c getopt.h getopt1.c io.c limits.h util.c version.c
The files regex.c and regex.h have been removed; see below.
This file (README.PC) is the only new file in this directory.
The following new files are in the pc-files subdirectory:
diff.man manual page for diff (actually both man pages contain two,
diff3.man manual page for diff3 the BSD version and a GNU addendum)
Makefile.os2 Makefile for OS/2 1.x and MS C 6.00
diff.def OS/2 linker definition file for diff
diff3.def OS/2 linker definition file for diff3
diff.bad OS/2 binder response file for diff
diff3.bad OS/2 binder response file for diff3
diff.patch patches for changed files from GNU diff 1.15
Makefile.msc Makefile for MS-DOS and MC C 6.00
Makefile.tc Makefile for MS-DOS and Turbo C 2.0
tdiff.lnk Turbo C linker response file for diff
tdiff3.lnk Turbo C linker response file for diff3
diff.cs compiler shell description file for diff under OS/2
diff3.cs compiler shell description file for diff3 under OS/2
(Note: compiler shell is a separate shareware program
from me that replaces the standare make utility)
merged.c the merged-diff-patches from Chip Rosenthal
alloca.asm alloca() routine for Turbo C
hrealloc.c hrealloc() routine from Thorsten Ohl
pipe.c pipe support for OS/2 (real) and DOS (simulated)
regex.c older version of GNU regex library that works with 16-bit
regex.h machines, the original current version is too big
Steps to do:
1. Compile as follows:
OS/2 and MS C 6.00: nmake -f pc-files\Makefile.os2
or if you have CS: cs pc-files\diff & cs pc-files\diff3
DOS and MS C 6.00: nmake -f pc-files\Makefile.msc
DOS and Turbo C 2.0: make -f pc-files\Makefile.tc
2. Test the programs.
Using these files, a version for OS/2 can be produced with MS C 6.00
that also runs under MS-DOS. The MS-DOS support here is only for people
that don't got the .EXE files (from a comp.binaries.os2 distribution)
and have to recompile under DOS.
This diff for the PC supports files up to 32767 lines each (about 1MB)
correctly (tested carefully !).
Some bugs are still in the Turbo C version, with huge memory support.
If someone fixes them, please send me patches.
