No you can't. This is from C99:

6.7.5.2 Array declarators

Constraints

In addition to optional type qualifiers and the keyword static, the [
and ] may delimit an expression or *. If they delimit an expression
(which specifies the size of an array), the expression shall have an
integer type. If the expression is a constant expression, it shall
have a value greater than zero. [...]

Which uses gcc.

I think they use a similar example in the spec, but with an array size
of one.
