I'm running both WinME and a Win98SE machines.

WinME: v1.3.13(CVS)
Win98SE: v1.3.12-2

Both are running the latest bash from the mirrors:
GNU bash, version 2.05b.0(1)-release

Both are running expr (GNU sh-utils) 2.0

Curious, this is the result on the Win98SE machine:
$ expr xposixmutexes :
'.*[^-_abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789]'

0

I take it this isn't what should have happened if something was

that error...

Yes, I'm always running the latest :-).  As a side note, eventhough
I'm regex-illiterate, I still know what I'm doing for the most part
;-).
