Thanks for the replies, you are right the function is being treated
something like:
	void test(int (*a)[1])

What's slightly strange is that if I make the array in main() const it
compiles without the warning.

Obviously removing the const in the test() argument is ok, it's a pity
you can't mark a multi-dimensional array parameter as const, it's just
part of the leagacy of C's pointer/array loose definition.
