	This may be a limitation of G++ on AIX.

	Does you application require runtime type information?  If not,
you can compile with -fno-rtti.

	You do not specify which update of AIX 5.1 you are using.  If you
install the weak symbol feature for AIX 5.1 and rebuild GCC to utilize it,
GCC might be able to handle C++ typeinfo language features better.  I
suspect the prebuild binaries on UCLA's aixpdslib are not built with AIX
weak symbol support.
