+; Compatibility wrapper for cc65's mul40 or _mul40 library routine.
+; Necessary because cc65 <= 2.17 has "mul40" as part of its atari
+; library, but 2.18 and up made it a C-callable routine on all
+; platforms, meaning its name grew a _ in front, "_mul40".
+
+; The .VERSION pseudo-variable is documented as "major version
+; times $100, plus minor version times $10". Whoever came up with
+; this design must have thought the minor version would never exceed
+; 15... starting with 2.16, the minor nybble overflows into the major
+; one, meaning cc65-2.17's .VERSION is actually $0310. Which is fine,
+; so long as there's never a cc65 major version 3.x (if this happens,
+; versions 3.0 and 3.1 will fail to build this correctly, then 3.2
+; will work again).
