The GCC folks only seriously consider bug reports against their own
snapshots and CVS, so technically, it's a NetBSD bug. 2.95.3 is
ancient, and probably not worth the trouble to maintain, however,
especially where there's a known work-around. The interesting question
is, does the bug still exist in 3.3.1? If so, then it seems that you
have analyzed the problem well enough to make a good report directly
to the GCC folks. If it's fixed, on the other hand, then it will
quickly become a moot issue. GCC 3.3.1, the latest release from GCC,
builds out-of-the-box on NetBSD 1.6.1, and will soon be part of
NetBSD-current. It's also packaged in pkgsrc a handful of different
ways, as just one would never do.
