+/** Very like some remnant from the 8086, 286 and 386 days of DOS, OS/2 and

+ * point support the library provides, probably especially as it comes to
+ * printf and scanf conversion but probably also emulation/real hw.
+ *
+ * Found some old 16-bit and 32-bit MSC C libraries (probably around v6.0)
+ * which all seems to define it as 0x9876.  They also have a whole bunch of
+ * external dependencies on what seems to be mostly conversion helpers.
