The link you supplied points to potential problems if there are 
inadequate sequence points in the presence of side-effects. It doesn't 
mention comma clauses, does it?

I do not see the problem when providing adequate sequence points ( what 
AFAIK is the sole purpose of comma's in a statement -- comma clauses ), 
and when the terms are constants or simple expressions (so no side-effects).

Am I missing something embarassingly obvious ( comma got removed from 
the C standard or something )?
