+$!	If you are using a version of GCC that supports global constants
+$!	you should remove the define="const=" from the gcc lines.

+$!	Caution:  Versions 1.38.1 and earlier had a bug in the handling of
+$!	some static constants. If you are using such a version of the
+$!	assembler, and you wish to compile without the "const=" hack,
+$!	you should first build this version *with* the "const="
+$!	definition, and then use that assembler to rebuild it without the
+$!	"const=" definition.  Failure to do this will result in an assembler
+$!	that will mung floating point constants.
+$!
+$!	Note: The version of gas shipped on the GCC VMS tapes has been patched
+$!	to fix the above mentioned bug.
