for Sun acc 3.0 under SunOS4.
Changes to improve handling of runtime common symbols
under SunOS4.
* minsyms.c (get_symbol_leading_char): New routine to determine
the leading symbol character for an objfile.
(prim_record_minimal_symbol_and_info, install_minimal_symbols):
Use it.
* objfiles.h (rt_common_objfile): New global, points to objfile
containing the runtime common minimal symbols.
* objfiles.c (free_objfile): Mark rt_common_objfile as
unallocated before freeing it.
* solib.c (allocate_rt_common_objfile): New routine to allocate
an objfile for the runtime common minimal symbols.
(solib_add_common_symbols): Allocate an objfile for the runtime
common symbols if necessary and put common symbols into it.
Clean up code and comments.
(solib_add, special_symbol_handling): Cleanup comments regarding
runtime common symbols.
* stabsread.c (scan_file_globals_1): New routine, contains
old scan_file_globals code. Checks if there are any unresolved
global symbols before starting the expensive minimal symbol table
search.
(scan_file_globals): Now calls scan_file_globals_1 for the passed
objfile and eventually for the runtime common objfile. Complains
about any unresolved global symbols and removes them from the
global symbol chain to avoid dangling pointers into the symbol
table if the symbol table is reread.
objfile not symfile_objfile.
* symtab.h, minsyms.c (minsyms_sort): New function.
* objfiles.c (objfile_relocate): Call it.

redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and

* 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>.
