'usr/bin/expr.exe' is provided by sh-utils ( 
http://cygwin.com/cgi-bin2/package-cat.cgi?file=sh-utils/sh-utils-2.0-2&grep=expr 
)

I'm not exactly sure if it is a builtin of tcsh/bash/ksh/ash, but I do 
know it should be available outside a shell on a system that uses SUSv2 
( http://www.opengroup.org/onlinepubs/007908799/xcu/expr.html ) as a 
guideline(which Cygwin as a distribution tries to do AFAIK).

When I wrote my earlier post I didn't have a web connection but I did 
double check on a HP-UX ksh terminal that it should work as I thought it 
would. It even works using from a cmd.exe shell from W2K.
