Cool! I know a lot of people who have had problem with the QNX
maintained version of gcc.

Probably. Look at config.guess and config.gcc to see how it
is done for other similar platforms.

Most of the active development is being done on the 3.x version.
Bernd Schmidt <bernds@redhat.com> is the maintainer of the 2.95 tree,
but that tree is basically in maintenance mode, so not much is going
on there.
Look at the instructions at http://gcc.gnu.org/contribute.html for
instructions on how to prepare patches to be submitted to the
gcc-patches@gcc.gnu.org mailing list.

You can do that if you want, there are different projects and people
who have maintained their own patches to GCC before. The FSF GCC project
always appreciates help though!
If you could go to http://gcc.gnu.org/cvs.html, and try integrating
QNX RTP support into the latest GCC 3.1 tree, and submitting patches, that would be
really cool. I know people who have had problems with GCC under QNX,
especially for C++.
