You didn't follow the directions fully.

Your example works fine with "-std=c89", or some alias for that: c90,
iso9899:1990, -ansi.  Also with iso9899:199409, gnu89 and gnu90.

You have to tell the compiler the maximum level the code has been
written for/to/at, and if that's c90, well that's c90 and no more.
