I can say that the cygwin native 3.0.3 compiler works for a lot of what I
have tried, but I have not tried rebuilding cygwin itself as yet. And while
I haven't tried it yet with a linux->cygwin cross.  I was trying to build a
cygwin->linux cross of gcc 3.0.3 without bringing over my glibc from my
linux box.  Yes I'm a masochist.  My ultimate goal was to do some much
needed compiling with spare cycles while doing "real work" *cough* *cough*
in Windows.

Exact same results here. I agree that libstdc++-v3 is VERY confused wrt
newlib.  It doesn't appear that Cygwin+newlib+gcc-3.0.3 is a good
combination.  Even building gcc cygwin->linux with the --with-newlib
configuration argument seems to seriously choke.  It still goes off looking
for glibc headers.  I decided that 3.0.3 needed to ripen some more.
