Well, I don't think this is such a good idea. What if the Cygwin port
of ``cp'' is suddenly made to work correctly with that filesystem
voodoo Cygwin does, but other programs are still defunct?

Instead of chasing possible problems with Cygwin's little magic trick,
isn't it better to just try to detect it and circumvent it completely?
(As I try to do with the AC_EXEEXT patch.)
