  Yes, building the bootstrap compiler needs nothing but the headers (and of
course libraries too) for the *host* system that it will run on.

  Whether those are "installed kernel" headers, because you're cross-compiling
from a linux box, or win32 headers when you're building your cross-compiler on
a win32 box, makes no odds; the point is, it's the local system's headers that
are needed, and nothing for/from the *target* is required at all.
