I'm not sure why you directed your problem directly to me so I'm copying the
list on my reply. If you want this to work then _you_ will have work on
_porting_ it. I don't know of anyone working on this particular problem as rcs
and cvs are used more for source code management rather than binary data
management. Others, feel free to comment if you've gotten diffutils and rcs to
correctly work for binary files on Win32.
I'll suggest that you use -mno-cygwin or mingw32 to use the native api's rather
than the cygwin library. Yes, it is possible to have these tools in native
mode. I have successfully built diffutils and rcs under mingw32. I've built
cvs under mingw32 but it didn't work correctly and I never got back to it.
None of these build without much tweaking under Mingw32 but it can be done.
Good luck,
Earnie.
