+	* configure.in (GUILE_FUNC_DECLARED): Name the cache variables

+	The type of the argument to usleep varies from system to system,
+	as does the return type.  We really shouldn't be redefining usleep
+	at all, but I don't have time to clean that up before the 1.3
+	release.  It's on the schedule for afterwards.
+	* configure.in: Cache results from usleep return value test.
+	Test for the type of the usleep argument, and cache that too.
+	* acconfig.h (USLEEP_ARG_TYPE): New macro.

 	* simpos.c (scm_software_type): Procedure deleted.  This isn't the
 	right way to handle system variation.  Autoconf's approach is the
 	way and the light.
