In the original posting I stated:

This is in error.  The Dhrystone measurement should have been 
5717.0 Dhrystones per second.

I now have confirmed this value using the PC532 as a host.  The
value is independent of wheither or not -DREG=register is 
defined.

That's because gcc ignores the register keyword and does its own
register allocation.

Except it wasn't cross-compiled by gcc -- it was cross-compiled
using the LSS C compiler.  LSS stands for Logical Systems Software and
is the one that comes with the Transputer Educational Kit aka TEK.  

Sorry if I wasn't clear.
