Possibly, this issue should be broached with the libstdc++ maintainers.
In my testing, I have moved to installing each gcc version in its own
directory.

I should note again that 3.3 has a ABI change in the passing of small
structures.  It also contains a fix for function pointer comparison.
As glibc does function comparison in a number of routines, it needs
recompilation with 3.3 to work correctly.  Then, I believe gcc needs
to be rebuilt as libstdc++ depends on the thread implementation.  The
last glibc linuxthread code that I downloaded was still broken.  I know
Carlos has a patch in the works.
