It does? [ checks standard... ] Oh wow:

6.8.5 Iteration statements

Syntax

iteration-statement:
while ( expression ) statement
do statement while ( expression ) ;
for ( expr-opt ; expr-opt ; expr-opt ) statement
for ( declaration ; expr-opt ; expr-opt ) statement

I'd always thought this was only in C++. This alone might be a sufficient
reason to drop C89 compiler support ...
