I went through this recently at work for some reason, so I consulted my handy 
copy of the C99 spec.

Section 6.5, paragraph 3:

"The grouping of operators and operands is indicated by the syntax.  Except as 
specified later ( for the function-call (), &&, ||, ?: and comma operators), 
the order of evaluation of subexpressions and the order in which side effects 
take place are both unspecified."
