| P.S. Gaby - why isn't 'volatile' portable?  All it means is "don't optimize
| this".

Portable libraries best avoid 'volatile' because its semantics is
implementation-defined.  What constitutes an optimization varies from
one compiler to another, from one version of the same compiler to 
another...

There is a well known OS whose chief maintainer rejects any patch that
contains 'volatile'.
