+	Simplify m/intel386.h.
+	* m/intel386.h (CRT0_DUMMIES): Remove, inline value in the only
+	user: ecrt0.c.
+	(SOLARIS2): Remove LOAD_AVE_TYPE, LOAD_AVE_CVT, LIBS_MACHINE, unused.
+	(USG5_4): Move LOAD_AVE_TYPE, LOAD_AVE_CVT, FSCALE definitions to
+	the only user: s/unixware.h.
+	* ecrt0.c: Remove #ifndef static.  Inline CRT0_DUMMIES definition
+	from m/intel386.h.
+	* s/unixware.h (LOAD_AVE_TYPE, LOAD_AVE_CVT, FSCALE): Definitions
+	moved here from m/intel386.h.
+
 	* m/mips.h: Remove #if 0 code.
