* dwarf2read.c (typename_concat): Use (char *) NULL terminated stdarg
	list for the obconcat call.
	* mdebugread.c (parse_symbol): Likewise.
	* stabsread.c (define_symbol, read_member_functions, read_cpp_abbrev):
	Likewise.
	* symfile.c (obconcat): Replace the s1, s2 and s3 parameters by `...'.
	New variable ap.  Remove variables len and val.
	* symfile.h (obconcat): Likewise for the prototype.
