They work as long as your cyg*.dll match the svn-installed cyg*.dll.
The cyg*.dll manages some system-global data for the process
tables. It needs this data to implement fork(2), ps(1) friends. All
cyg*.dll's on the system _need_ to agree on the structure of this
system-global data. As soon as they do not agree on that, your system
is likely to crash. Please check the cygwin-FAQ for a better
explanation about this issue.

I think the proper way would be to provide _two_ packages like xemacs does:

1. first package is the native Win-Application which contains native
   diff.exe and diff3.exe
2. second pakage is a cygwin-package installed with the cygwin-setup
   and contains a "require: diff diffutils" in its package

This way you could install the one you need and anyone would be
happy. You could install even both!

The only question is: will new path-conversion-issues arise with a
cygwin package (which contains its own path-conversion-concept)?
