Against DJGPP version: 2.01

Abstract: patch gets ENOENT with Win95/LFN=Y
patch gives no end of trouble when LFN=Y (I have numeric tails turned
OFF): witness:

C:\TEMP>set lfn=n

C:\TEMP>patch < a.pat
Hmm...  Looks like a new-style context diff to me...

I think this is a user/Win95 bug.  The user says he disabled numeric
tail.  Patch backs up `foo.bar' in a file called `~foo.bar'.  I
suspect that when numeric tail is disabled, Windows 95 cannot grok
such names.

FYI, Microsoft's official line is that when you disable numeric tails,
you are on your own, and they don't consider any strange effects of
this as their bugs.

Recompile with the latest release of libc.a in djdev201 (31st Oct 96).
patch.exe was compiled before libc's _rename.c file was corrected
for misbehaviour under Win95 with LFN=y.

Fixed in version on 04/13/1999 08:00:55
