configuring libstdc++ fails:
error: No support for this host/target combination
This is a regression at least against gcc-4.4.
I'm not really sure, but I think sometime last year this even worked for
gcc-4.5.0.

I haven't tried a whole lot of cross compiler building. There's no reference
to cygwin anywhere in crossconfig.m4, so perhaps we need --with-newlib?

The identical setup works for gcc-4.4.2 and gcc-4.4.3
I'm a little bit short on time at the moment, but I try to dig into it further.
To find the change that caused the different behavior probably will help.

Sorry guys, my fault. Indeed I missed --with-newlib.
So, closing as invalid.
