It's going to be hard.  gcc 2.95 doesn't support using x86_64 as a host,
so you're going to have to build in in a 32-bit virtual machine or by
using mock.

You'll have other problems too.  gcc back then wasn't so standards-
clean as it is now; we have a lot of warnings and better diagnostics
that have allowed us to clean up gcc.  I don't know why you got that
particular message, and as I said I can't look at your logs.  I might
have a try myself to build gcc 2.95 later today.
