Hi Vanessa,

ahh, this script was meant for build a cross tool chain on GNU/Linux
for mingw.

I've not tried to build it natively under MinGW - but you could try
using the same configure commands as with Cygwin.  It would be
interesting to see how far it gets!

The cross building script is fairly old now and I suspect the binutils
and libc to have changed quite a lot.  I'm not aware of any report -
but maybe someone has tried it..
