1. Anyone who can normally approve patches can approve patches that
fix regressions from previously released versions of GCC.
2. I will review and approve patches that do not fix regressions if
a) they appear safe
b) they fix very important problems, or
c) they add support for new platforms, language features, etc.
that we did not support before -- and that we cannot, therefore,
be regressing.
Please make your case explicitly; assume I know very little (a
good assumption!) and explain why your patch fits these criteria.
