ISO C90 and ANSI C89 are one and the same.

Variable length arrays we could certainly do without, if you can find
a clean way.  We are, however, using other C99 bits that we'd rather
not stop using, one of these being named initializers for structs, so
getting rid of variable length arrays with the sole purpose of making
the code closer to C89 compatible seems pointless.
