-# This high quality math library is intended to run on either a VAX in
-# D_floating format or a machine that conforms to the IEEE standard 754
-# for double precision floating-point arithmetic.
-#
-# WARNING: On machines other than the ones mentioned above, run the original
-# Version 7 math library, if nothing better is available.
-#
-# MACHINE indicates the type of floating point hardware you are using; legal
-# values are:
-#
-# vax		- for the VAX D_floating format, the default.
-# tahoe		- for the TAHOE double format.
-# national	- for those IEEE machines whose floating point implementation
+# ieee		- for most IEEE machines, we hope.
+# mc68881	- the, ahem, mc68881.
+# national	- for those ieee machines whose floating point implementation
 #		  has similar byte ordering as the NATIONAL 32016 with 32081.
-# ieee		- for other IEEE machines, we hope.
