The normal as which comes with cygwin gcc doesn't include the -G option.  So the above is finding the wrong as which I suspect is due to the \ versus / issue..

OK, my mistake.  I don't know about gcc-2.8.1 by Cygwin's gcc 2.95.3 
does understand both / and \ as path separators.  So I guess this could 
be an issue but I don't believe it's a general one.
