In short, because the method for detecting a Cyrix chip (checking to
see whether the condition flags change during a divide instruction)
does not differentiate between the various Cyrix CPUs, and the code as
it was submitted to me some time ago always calls then `486DLC'.  This
is basically harmless, but if someone knows how to differentiate the
models, please let me know.
