	You seem to be mixing two issues in your question: AIX weak symbol
support and current AIX 5L functionality.  AIX 5L as currently distributed
does not support weak symbols.  If weak symbols were implemented, these
failures should be fixed.

	Using XFAIL is inappropriate and just hides the problem which will
make it even more likely that G++ users will expect the functionality to
work.  Those testcases explore G++ functionality and G++ assumes weak
symbol support, so those tests should fail on targets without weak symbol
support.
