Yes that is a nasty cfront bug. Sorry. The code is legal C++ but I have
persistent problems convincing YACC about that.

Fortunately the workaround is simple:

	int spam() {
 	    auto double (*z)[4] = (double (*)[4])0;
	}

In general, if you get funny error messages in connection with pointer to
function declarations use a storage class specifier to help YACC.
