*Use a typedef rather than a macro definition for va_list. (The C standards specify that va_list is a type, although this would make a practical difference only if someone #undef'd it.) *Don't include a semicolon in va_start(), so it expands to an expression rather than a statement. This could make a difference in a construct like "if (...) va_start(...); else ...".
