bootstrap4 with 2.95.3

bootstrap4 with 2.95.3

[Paul Jarc]

I'm trying to build gcc 2.95.3 on a GNU/Linux machine.  (I had no
problem building and installing 3.1.1, but I keep 2.95.3 around for
certain things like the kernel and ncurses.)  When I use "make
bootstrap", I get some differences in 3 object files.  So started over
with fresh sources and an empty build directory and tried "make
bootstrap4".  This gives me:
[...]

How do I build the first stages without doing a comparison, so that
bootstrap4 will work?

I went ahead and did "make install" anyway, and used that installation
to do the 2.95.3 bootstrap again, and the comparison succeeded.  So it
seems 3.1.1 (which I used the first time) miscompiled 2.95.3.
