Give people a choice; compile two libm's on the i386. They should be

interchangeable shared libraries.

+# There are two options in making libm at fdlibm compile time:
+# 	_IEEE_LIBM 	--- IEEE libm; smaller, and somewhat faster
+#	_MULTI_LIBM	--- Support multi-standard at runtime by 
+#			    imposing wrapper functions defined in 
+#			    fdlibm.h:
+#				_IEEE_MODE 	-- IEEE
+#				_XOPEN_MODE 	-- X/OPEN
+#				_POSIX_MODE 	-- POSIX/ANSI
+#				_SVID3_MODE 	-- SVID
+#
+# Here is how to set up CFLAGS to create the desired libm at 
+# compile time:
+#
+# 	CFLAGS = -D_IEEE_LIBM		... IEEE libm (recommended)
+#	CFLAGS = -D_SVID3_MODE	... Multi-standard supported
+#					    libm with SVID as the 
+#					    default standard
+#	CFLAGS = -D_XOPEN_MODE	... Multi-standard supported
+#					    libm with XOPEN as the 
+#					    default standard
+#	CFLAGS = -D_POSIX_MODE	... Multi-standard supported
+#					    libm with POSIX as the 
+#					    default standard
+#	CFLAGS = 			... Multi-standard supported
+#					    libm with IEEE as the 
+#					    default standard
