Does the SYSTEM user have uid == 0? Does any user have an uid == 0?
If not then it does not matter anyway. I can just leave it as it is.
If in future some superuser concept might find it's way into Cygwin, this $SHELL stuff
is safe already.
Oh, I forgot to mention that I changed the rename() logic a bit.
rename("a", "b"): If "a" is really "a.exe" it is renamed to "b.exe"
rename("a", "b.suffix"): If "a" is really "a.exe" it is nevertheless renamed to
"b.suffix". The ".suffix" implies that the user knows what she's doing.
rename("a.exe", "b"): The ".exe" suffix implies that the user knows what she's doing,
too, so "a.exe" is renamed to "b"
This also holds for link().
I've taken that from UWIN, too.
