* builtins.def (DEF_LIB_ALWAYS_BUILTIN, DEF_UNUSED_BUILTIN): Delete.

	(abs, labs, fabs, fabsf, fabsl, abort, exit, _exit, _Exit):  Use
	the appropriate macro to define built-in function.
	(fmod,fmodf,fmodl): New built-in functions.

	* java/decl.c (java_init_decl_processing): Get soft_fmod_node from
	built_in_decls[BUILT_IN_FMOD] rather than define it ourselves.

	* doc/extend.texi (fmod,fmodf,fmodl): Document new built-ins.
