If you would like to help pretest GCC releases to assure they work
well, or if you would like to work on improving GCC, please contact
the maintainers at gcc@gcc.gnu.org. A pretester should
be willing to try to investigate bugs as well as report them.
If you'd like to work on improvements, please ask for suggested projects
or suggest your own ideas. If you have already written an improvement,
please tell us about it. If you have not yet started work, it is useful
to contact gcc@gcc.gnu.org before you start; the
maintainers may be able to suggest ways to make your extension fit in
better with the rest of GCC and with other development plans.
