You cannot have a statement before a declaration.  The problem in the code
above is the same problem in the following code:

int func(void) {
    int z;
    callme(&z);
    int y;
}

callme(&z); is a statement, which ends the declaration block.  "int y;" is
an error.

Replacing the two lines at top with "int dim = 3;" will work becuase it is
no longer a statement; it would then be a declaration with initializer.
