   I see your point. But... I don't do MS "visual" things, and I   
   hate the idea of adding a steam hammer just to smash a fly.   
   GNU g77 is what I've installed, for no special reason except   
   I'm familiar (or used to be) with /old/ FORTAN dialects .   
   well, it happens "g77" does NOT do inline ASM. Oh, I'm on   
   ia32, not amd64 btw.
