OK, for the moment lets forget about cygwin make.  The native build of 
make should have the same issue,
as it is calling stat which is provided in the winapi, but is slow.   
Can someone give me a pointer to where
I could put different calls into make just so I can try it and see if it 
helps.  Thanks.
