+	* config.in (HAVE_UINTPTR_T): Provide autoconf stub.
+	* configure.in (HAVE_UINTPTR_T): Test for system defining
+	uintptr_t and define HAVE_UINTPTR_T appropriately.
+	* regex.c (uintptr_t): Do not provide a definition if the
+	system provided one.
+
+	* regex.c (PREFIX): Provide an alternate definition for
+	non-ANSI/ISO compilers.
+	(ARG_PREFIX): Likewise.
