consider there may be a file compiled without -g screwing things up
(e.g. we are looking for the minimal symbol for "main" and we get the
one for "start" instead).

SYMBOL_INIT_LANGUAGE_SPECIFIC.

what SYMBOL_DEMANGLED_NAME used to do, directly access the C++
mangled name member in the language dependent portion of a symbol.
* symtab.h (SYMBOL_DEMANGLED_NAME): New macro that returns the
mangled name member appropriate for a symbol's language.
* symtab.h (SYMBOL_SOURCE_NAME, SYMBOL_LINKAGE_NAME,

basis. See comments in objfiles.h and details in ChangeLog. Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.
* All GDB files that #include defs.h: Removed stdio.h.
(defs.h): #include stdio.h.
This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion. (n.b.
many configurations don't build for other reasons.)
* minsyms.c (install_minimal_symbols): Add bunches to any
existing minsyms in the objfile. Avoid extra mallocation
by working directly in the obstack. Remove ignored `mainline' parm.
* coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
xcoffread.c: Change all callers.
* FIXME: We should be able to eliminate MAINLINE from all the
symbol readers now, with a small bit of work.
* valops.c, value.h: Lint.
* remote-vx.c: Add missing break; statement. Bugfix by
Michael Sclafani, <sclafani@src.dec.com>.
