Another Issue for 5.0

[Daniel Berlin <dan at cgsoftware dot com>]

IMHO, the overload resolution for DWARF2/STABS/all non-hp platforms should
really be fixed for 5.0.
I have patches to do this (in fact, i'm about to send another jumbo patch
to gdb-patches with it all combined so i don't have to keep emailing it to
people :P), with no regressions, well, actually, that's not true.
Some overload resolution things that were xfail before in the testsuite
now pass.
Sorry about that. I'll try to make sure i keep the broken things broken in
the future. :P

But, anyway, i get about 5-10 emails a week asking for those patches.
Even on HP using aCC, where overload resolution works, you get benefits
because i added support for references in overloads, and fixed a problem
where the compares against function names were whitespace sensitive where
they shouldn't have been (so operator [] would be considered the same
function as operator[] when we were hunting down overloads).

Maybe i'm biased, but anyone working on C++ programs would love it.

I'm starting to work on other C++ language support related things, if
anyone has any specific requests, let me know.
