which doesnt help, you still need to compile/assemble parts with something
else then MSs compiler, so how is that better then gcc?

btw, AFAIK the reason why *ASM is used in some projects instead of gccs 
inline asm is that the developers hate the AT&T style asm and prefer intel 
style, not that i disagree on the ugliness of AT&T style asm ...
