Bugs do not expire from GNATS.  If you just send them to gcc-bugs they
may get forgotten about.  You should not need any credentials to use
the gccbug script, included with every snapshot, to file a report in
GNATS.

None of what you said gives me any idea of what the bug actually is,
beyond some sort of problem with -march=pentiumpro -ffast-math and
Cygwin.  I see several reports in the gcc-bugs archive which seem to
be related to that combination of options, but I do not know which is
yours, or whether they've been fixed.  I'm going to assume that gcc
2.9[67] either crashes or generates incorrect code for some input or
other, with those options, and gcc 2.95.x doesn't.  If that is true,
then the bug is important never mind how rare it is.

But you have to tell us what the bug is, before we can fix it.
