and preached to the unwashed masses:

patch(1) on Win32 seems to insist on '\' rather than '/' in the paths in diffs. This is somewhat at odds with diff(1) which uses '/', even on Windows.

According to the manpage there is no option to change this behaviour.

I have d/l the sources but have yet to build it (am I correct that it needs gcc to build, i.e. won't build with MSVC++?) with the intention of making my own version that works with '/'.

Can anyone confirm that there isn't an undocumented option (cmd line or build) to make it use '/'? If there isn't, why is it that the Windows version works this way, especially when diff(1) DTRT?

What patch are you using? The Cygwin version works fine with '/'. I have
to assume that since you mention the "Windows version" that your talking
No, the one installed by the cygwin setup program:

Perhaps you should have used the -p or --strip option?

about a native port and not the patch that's available through Cygwin.
If that's a proper assumption, you don't have the right forum to discuss the Windows native version of patch. This list discusses Cygwin-related issues
