I noticed that my cygwin bash shell has $OS defined already, as "Windows_NT"
while uname -s produces CYGWIN_NT-5.0. 

Normally, I expect `uname -r` to say "5.0", but it gives another number,
presumeably a cygwin version.

bash-3.00$ uname -s
CYGWIN_NT-5.0
bash-3.00$ echo $OS
Windows_NT

I only ask because my Makefiles from Unix would prefer to have $OS either not
set, or be equal to uname -s. Is there a reason why these things differ?
(My Makefile's will get changed to cope...)
