I'm afraid you are mistaken.  In particular, the Microsoft C Language
Reference version 5.0 specifically mentions: "The sequential-evaluation
operator evaluates its two operands sequentially from left to right.  There
is a sequence point after the first operand.  The result of the operation 
has the same value and type as the right operand.  Each operand can be of
any type. ... The sequential-evaluation operator, also called the "comma
operator," [sic] is typically used to evaluate two or more expressions
in contexts where only one expression is allowed."
