How's it built now?

With Cygwin gcc and the -mno-cygwin option, using's w32api.

It doesn't use -mno-cygwin. How could it? The build uses the latest gcc 4 which doesn't have that option. It uses the Cygwin gcc either natively

Okay, with you so far.

or as a cross-compiler.

Huh? Do you mean that we use cygwin's gcc as a code generator, and turn off everything that makes it "cygwin":

(e.g. -nostartfiles -nodefaultlibs -nostdlib -nostartup -nostdinc -nostdinc++ etc),

and -- because we build in a tree that includes w32api/ and mingw/ -- explicitly add those things that would make it a "mingw" compiler:

(e.g. -I ${srcdir}/winsup/w32api/include -I ${srcdir}/winsup/mingw/include -L ... ${builddir}/winsup/mingw/crt0.o etc)

I *think* that's what you meant -- but it's an odd definition of the term "cross compiler". It's more like: we've tied it up and tortured it until it agrees to act like a cross compiler.
