+2003-07-12 Zack Weinberg <zack@codesourcery.com>
+
+ * 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.
+
2003-07-12 Nathanael Nerode <neroden@gcc.gnu.org>
* fixinc/inclhack.def (struct_sockaddr): Avoid "fixing" sockaddr_in
