Re. Building latest snapshot using latest tools fails for m68k Coldfire under cygwin

[Ian Caddy]

Hi,

This looks like the problem that was reported some time ago about the
byte swapping provided in m68k.h

The function that would be called is:

CPU_swap_u32 or CPU_swap_u16

A patch has been put forward, but if you want a copy I can forward a new
m68k.h offline.  The instructions that are in the file are not supported
in the Coldfire processor.

Talk to you soon,

Ian Caddy
