--- Comment #18 from Cary Lewis <cary.lewis at gmail dot com> ---
I took your advice, and attempted to bootstrap gcc 4.2.4 with languages=c,c++

I received a very similar error:

There must be something unique about the SCO environment that leads to this
error.

Maybe the way that the gcc 2.95.3 compiler gets installed.

I tried building gcc (c++) 3.4.3 with both the gcc 3.4.3 gcc compiler and the
2.95.3 gcc compiler.

Any other suggestions?
