+  * source/vm/hvm.c
+    - Changed byte by byte copy used in PushString to memcpy,
+      because the side effects of code like szTemp[w++] = szText[w]
+      is compiler dependent. Borland C++ 3.1 (in C mode) copies byte
+      0 to byte 0, etc., but IBM Visual Age C++ 3.0 (in C++ mode)
+      copies byte 1 to byte 0, etc.
