I have some doubt here.  Cygwin always checks for "foo" first.
Only if it doesn't find "foo", it checks for "foo.exe", then
for "foo.lnk" and last, for backward compat, for "foo.exe.lnk".

In the POSIX realm, "foo" =3D=3D "foo.exe" =3D=3D "foo.lnk".  The search it=
self
is indiscriminately, because Cygwin can't know if you're looking for
"foo" or "foo.exe" or a symlink "foo" using the .lnk suffix.
