>Description:
I downloaded and compiled gcc 2.95.2 with only minor problems
but discovered that may favorite C++ program would seg fault
instantly when started, apparently in the valarray library.
Suspecting a problem in the stdc++ library, I downloaded
libstdc++ 2.90.8, copied into the gcc source tree as
directed, and attempted to recompile gcc with the new library.
I got the warnings about an inability to inline three
functions, which were converted into errors, causing the
compilation to fail.

The pertinent part of the error messages is as follows:
