You CAN'T have a directory and an executable sharing the same name on Linux, so why should you try the same thing on cygwin? Given that cygwin attempts to handle '.exe' as a necessary evil, and tries to recognize executables when the suffix is omitted, you are basically confusing cygwin by creating a directory and an executable with the same name. That said, there's probably room for improvement for recognizing the situation, and trying to be smarter when both directory and .exe executable exist; and the patch may need to be in coreutils rather than in cygwin1.dll (since cp is doing some extra legwork for .exe magic in the first place). Good thing I'm building coreutils 8.9 today :) -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
