This is a known problem. Some versions of Microsoft compilers are
supposedly capable of generating standard COFF debugging when you
give them a flag /Z or /Zi or some such, but I've never observed
this myself personally.

Mangling algorithms are generally very compiler-specific. GDB could
in theory be taught to understand pdb files, and there is at least some
debug info documentation on MS' CDs, but it would be a major project,
even for a GDB expert.
