Porting GCC to an operating system is usually nearly a zero-cost task
since there's so little of the compiler that depends on the operating
system.  Usually all you have is a couple of definitions of things like
object file and debugging format definitions and symbol name rules, so
this isn't saying much.

But that's the biggest issue in such a port.
