Maybe I should have mentioned that the as its getting to is the cygwin 
default as.  If I go to the correct directory and run as from there with 
--help it does include the -G option.  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..

Thanks for the idea though..
David.
