Thanks so far.

Right now, I do this:

$ CC='gcc -mno-cygwin' CXX='g++ -mno-cygwin'
../binutils-060628/configure --build=i686-pc-cygwin
--host=i686-pc-mingw32 --prefix=/opt/mingw

But I get stuck like this:

gcc -mno-cygwin -c -DHAVE_CONFIG_H -g -O2 -I.
-I../../binutils-060628/libiberty/../include  -W -Wall -pedantic
-Wwrite-strings -Wstrict-prototypes

I suppose it's safe for me to temporarily use ar (which is cygwin's
/usr/bin/ar) but if you're of an other other opinion, pls let me know.

however, after that problem, I get to a more tricky one:

/bin/sh ./libtool --mode=link gcc -mno-cygwin -W -Wall

I understand this is binutils pakage's libtool that needs tweaking to
use 'gcc -mno-cygwin' somehow instead of 'lib' to create the
libbfd.lib ... any ideas on what to do about that issue?
