	initializer.
	(ada_language::value_print): New member function.
	* c-lang.c (c_language_data): Delete la_value_print initializer.
	(cplus_language_data): Likewise.
	(asm_language_data): Likewise.
	(minimal_language_data): Likewise.

	* language.c (unk_lang_value_print): Delete.
	(language_defn::value_print): Define new member function.
	(unknown_language_data): Delete la_value_print initializer.
	(unknown_language::value_print): New member function.
	(auto_language_data): Delete la_value_print initializer.
	(auto_language::value_print): New member function.
	* language.h (language_data): Delete la_value_print field.
	(language_defn::value_print): Declare new member function.
	(LA_VALUE_PRINT): Update call to value_print.
	* m2-lang.c (m2_language_data): Delete la_value_print initializer.
