aclocal.m4 (gcc_AC_CHECK_TYPE): Clone of AC_CHECK_TYPE... 

	* aclocal.m4 (gcc_AC_CHECK_TYPE): Clone of AC_CHECK_TYPE,
	uses three-argument AC_DEFINE so no acconfig.h entries are
	needed.
	(_gcc_COMPUTE_GAS_VERSION): Also provide gcc_cv_gas_vers
	which contains the GAS version number as a scaled integer.
	(gcc_GAS_VERSION_GTE_IFELSE): Use gcc_cv_gas_vers.  Add
	ability to check for ELF assembler.
	(gcc_GAS_CHECK_FEATURE): New macro.
	* configure.in: Use gcc_AC_CHECK_TYPE.  Rewrite all
	assembler feature checks using gcc_GAS_CHECK_FEATURE.
	Use three-argument AC_DEFINE everywhere.
	* acconfig.h: Deleted.
	* config.in, configure: Regenerate.
