It is a true cross. The first thing I did was to build a MinGW native
version.

I'm willing to make the changes but I would like to merge them with the
cygwin port so that only one source tarball is necessary. The main
difference of course is which runtime library to use. I had some
strange configurations where configure thought that I had vfork.h and
stabs.h and I of course don't. I did the Q&D workaround on these.

And all of the other binutils utilities. Binutils just needed the
--target=mingw32 switch to build it. Also, I've currently lumped the
mingw-runtime and w32api headers and libraries together into the cross
path as well, I probably should look at soft linking these instead.
While I'm on the subject of configuration what would a preferred
--prefix be? I'm thinking --prefix=/usr/cross just in case someone
wants to contribute a cross-compiler for more than just MinGW; but there
certainly wouldn't be anything out of line with --prefix=/usr either.
Earnie.
