Yes, it should be possible to go this route.
You're building a stage 1 compiler that is a mingw binary, producing cygwin
executables, i.e. host=mingw, target=cygwin. The configure script doesn't
understand cross-compilation, but you should be able to edit mk/config.mk after
configuration to set up the right host/target values, and then build away. I'm
sure you'll have to fix a few things along the way - this isn't something we
test on a regular basis (in fact, ever).
