symbol types are, by definition, in the .data section, so it is
correct to use SECT_OFF_DATA (objfile) here, not data_sect_index.
If there is no .data section, there should be no N_DATA or N_DATA
| N_EXT symbols.

* dbxread.c (process_one_symbol): Only record line 0 if one or
more sline entries have been seen for the function.
From Jim Ingham <jingham@apple.com>:
* dbxread.c (process_one_symbol): Use last_function_start rather
than function_start_offset to find the real beginning of the
current function. The latter is just the text section offset on
some systems, the former is always the real function start.

(dbx_psymtab_to_symtab): Relocate the stabs data if necessary.
(read_ofile_symtab): Use stabs_seek.

that symbol if we are already at the top of the context stack for
a function-end N_FUN (this would imply an umatched RBRAC). Ditto

objfile_relocate to miss them. This is fixable, but the work that
the change was supposed to prepare GDB for never got done anyway.
* symtab.h (find_stab_function_addr): Kill extern.
* minsyms.c (find_stab_function_addr): Remove from here...
* dbxread.c: ... to here, and mark it static.
