Hy Jim,

I'm experiencing similar problems, while trying to build a new gcc-g++
compiler on linux, in 'libstdc++-3' I get following errors, and
compile exits :

And this is a gcc3.3.2 too I'm trying to build with, but it uses its
own included headers, so I guess it might not be related to the
compiler(system installed gcc) the inital xgcc(compiler used to
compile new g++ with) is built with.

I haven't figured out what the problem might be though ... but it
sounded similar, so maybe this might even help your search for the
clue, and mine too

bye,
gert

What's wrong with this one? I use it without problems.

Just install the binutils and the gcc package.
