Well, 2.12.1 is in egcs' infrastructure directory. Given that
someone (you?) went out of their way to do that, we need it for some
reason. Though why that is may be forgotten... :-)

I did a diff of the ChangeLogs and included it below. I think
the changes are minor. (Perhaps the hpux9 change is the reason we
upgraded? The SHELL stuff and AC_FUNC_VFORK also look useful.)
Anyway I'll put together a patch requiring 2.12.1. If you feel 2.12
is better, I can fix that before installing it.
