* dbxread.c (process_one_symbol): Handle N_FUN symbols

	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.
