There is a fellow working on adding support to gcc for
using spawn instead of fork when running the subprocesses
inside gcc on windows (without cygwin).  That's probably
the way to go if you want speed.  But I have no idea how
easy it is to build a mingw host, linux target cross-compiler.

A patch that seems to add spawn support is at:

Not sure what the status is.
