I wouldn't recommend to compile new code with 2.95 just because it is
faster. It doesn't do standard C and misses many broken constructs which
are caught by newer compilers.

It may still have some use for regression tests, and for old code
without a prospect of getting updated. I don't know how relevant
those cases are for Debian.
