* c-typeprint.c (c_print_type): Assume demangled arguments

	if a '(' is found in varstring, Looking for ')' at the end of
	varstring did fail with demangled const member functions, which
	have a trailing `const'.
	* remote.c (get_offsets, putpkt):  Change to `char' buffers,
	to avoid errors when compiling with DEC c89.
	(remote_wait):  Cast to `char *' before passing buffer to
	fputs_filtered, to avoid errors when compiling with DEC c89.
	(remote_wait):  Do not return inferior_pid by default, this
	statement is never reached, which causes warnings from some
	compilers.
	* stabsread.c (scan_file_globals):  Ignore static minimal symbols.
	* symfile.c (load_command):  If called with no argument, try
	to get the filename from the executable file.
	(generic_load):  Remove check for NULL filename, it is done
	in load_command now.
