-mno-cygwin with newer GCC?

Hi,

I'm trying to use -mno-cygwin with a Cygwin GCC-3.0.2 that I built from
sources. It seems that there are some preprocessor symbol definitions
missing, for example:

_U=01 _L=02 _N=04 _S=010 _P=020 _C=040 _X=0100 _B=0200 // for ctype_base
_GLIBCPP_HAVE_MBSTATE_T

it gets the wrong definition of
   _GLIBCPP_HAVE_ACOSF
et. al. from std_cmath.

Is there a way to make this work?
It seems to me that the MINGW community (and Cygwin for that matter) is
pretty committed to gcc-2.95.x, but I want the improved C++ compiler
available with 3.0.2. Is anyone out there doing a similar thing, or am I
completely out on a limb?

TIA,
Dave

Speaking as a mingw developer, I am committed to a GCC 3.1 for mingw in
April 2001.
