	Fix the `stopped language detection' testcase for gcc-4.5.
	* dwarf2read.c (read_partial_die): Set also LANGUAGE_OF_MAIN.
	* symfile.c (set_initial_language): Move variable filename to a more
	inner block.  Prefer LANGUAGE_OF_MAIN.
	* symtab.c (language_of_main): New variable.
	(set_main_name): Always reset LANGUAGE_OF_MAIN.
	* symtab.h (language_of_main): New declaration.
