Hi all,
this is a port of patch-2.0.12g8 (GNU version 12.8 of patch 2.0)

It was compiled with gcc 2.3.1 and the mintlibs pl 26, using the
-mbaserel and -mpcrel options, so it should be sharable under MiNT.
(Not that you'd be likely to use two patches simultaneously...)

This is the second port of patch I made in two weeks. The reason for this
is that the CR / CR+LF bug bit me. If a file was in MS-DOS format and the
patch in Unix format (or the other way round), patch would refuse to work,
as the files did not match. While patch could be forced to work by using
the -l option (ignore all whitespace differences), the resulting file
would be in mixed MS-DOS and Unix format. Pure-C hates this, gcc ignores
this kind of stuff. Editors often complain.

Basically, there are two solutions to this problem:
- Force the files and the patch to be in the same format.
  This is what I do when patch complains; I don't use the -l option.
  In this case, you should use the normal version of patch, 'patch.ttp'.
- Change patch to ignore such input differences and write out files
  in either MS-DOS or UNIX format, according to your UNIXMODE environment
  variable. As patch normally reads long chunks of file in binary mode,
  this would be hard to fix. I took advantage of another option: patch
  resorts to what it calls 'plan B' when files are too long, and reads
  all files line by line, using fgets() and fputs(). So I forced patch
  to always use plan B, even though this is somewhat slower and forces
  the use of temporary files.
  If you won't unx2dos your files, you should use the 'plan B' version
  of patch, 'bpatch.ttp'.

The file `patch.man' is a manual page for the patch command. A full manual
for patch, diff and cmp is available with the diff 2.1 package.
