Possible, but with more headaches than it's worth.  What I would do if
you want to use MinGW to host a Cygwin cross is to create a cross
compiler.  I.E. configure --target=i686-pc-cygwin --host=mingw32
--build=mingw32

You'll need both binutils and gcc.  Then you can just `CC=cygwin-gcc
configure' when you want to build for Cygwin.

Umm... See above note.

I don't know where libiberty.lib came from.  MinGW ships libiberty.a and
that comes from building GCC.  Please note, using libiberty in your
programs makes them GPL.
