Hello,

Ref: RFA symtab: Fix for PR c++/1267 ("next" and shared libraries)
http://sources.redhat.com/ml/gdb-patches/2003-07/msg00354.html

The change unfortunatly broke IRIX 6.5's host compiler which is using 
mdebugread :-(  That code was looking for a symbol in the absolute 
section "*ABS*" but the PR/1267 change was causing *ABS* symbols to be 
ignored (find_pc_section didn't return an absolute section).

Since the underlying problem with PR/1267 was with the frame code 
needing a minimal symbol that was in the same section as the frame's PC, 
and that code [indirectly] calls lookup_minimal_symbol_by_pc, I moved 
the find_pc_section call to that function.

Tested on i386 GNU/Linux (dwarf 2) with no regressions.
Tested on PPC NetBSD (stabs) with no regressions.
Tested on IRIX and all the warnings, and many failures, disappeared.
See gdb/1519 for how to exercise the bug.

ok?
Andrew
