The stat() function call will locate a file with no extension and one
with a .exe extension.  Obviously, the spawn() and exec() calls do
something similar.

The problem is that if you do a stat("ls", &st) it will succeed but
open("ls", whatever) will fail.

install.exe in the next version of cygwin will be ".exe" aware.

It hasn't been done before now because, ah, we haven't had an official
net release in a long time.  The Cygwin CD version does use this version
of install, however.
