This problem still exists in the coreutils-5.2.0-1 package that I have 
recently posted on cygwin-apps.

I've been looking at the fileutils-4.1-1 and fileutils-4.1-2 source code 
and AFAICT there has been some .exe handling code ripped out between 
these versions. I assume it was problematic but I haven't been able to 
dig up a bug report that explains why it was taken out.
