This appears to be an endianness issue: on a little-endian system 
(including x86) the Match[] entries only contain the LS byte of a 
widechar and on a big-endian system (incluing PPC) they only contain the 
MS byte. Practical result is that things look OK on x86 until the match 
contains a value > #$00ff.

I'm putting test data together for various CPUs and will raise a bug.
