Re: RFA: don't use minsym name when searching block
I've committed the following, which differs from my original patch:
1) it fixes the analogous uses in the HPPAHPUX block, and
2) it includes comments explaining why using the minsym name is
inappropriate.

* symtab.c (lookup_symbol_aux): In the cases where we find a
minimal symbol of an appropriate name and use its address to
select a symtab to read and search, use `name' (as passed to us)
as the demangled name when searching the symtab's global and
static blocks, not the minsym's name.
