If I were a strict GNUist, I'd have to answer that it isn't out job to
make life easier for those who don't provide source.  But seriously, it
will be up to KAI or Comeau to provide workarounds; it was never in the
egcs charter to support linking with other compilers.

This can't happen yet.  The C++ ABI can't be stable until we have
a complete ANSI compiler (including namespaces).  Besides, thre
are still more improvements to be had.  The current name mangling
scheme could stand improvements so that templat class names don't
come out so huge; egcs should not give up the right to makes such
improvements.
