Undefined external in test g++.pt/ptrmem2.C

[Steve Ellcey <sje at cup dot hp dot com>]

I have a proposed change to the test g++.old-deja/g++.pt/ptrmem2.C.
This test fails on my platform (IA64 HP-UX) because we need to generate
an external statement for globals (functions in particular) in order to
use the HP linker and g++ does so via assemble_external.  So g++
generates an external statement for the function S::h but this function
is never defined (or called), thus we fail to link.  My proposed fix is
to define S::h.  The other option would be to modify GCC to only call
assemble_external when we see a call to the function, not when we see a
definition, but I don't know if that is practical or not.

Obviously, this is only a problem on platforms that define
ASM_OUTPUT_EXTERNAL.

Any comments?  If it looks good can someone check it in?
