Parsing an int(x) parameter

Here is a simple function with one int parameter:

void f(int x) {}

f(42);

And here is another function with one int parameter:

void g(int(x)) {}

g(42);

Now let us define x to be a type:

typedef int x;
void h(int(x)) {}

h(42);
// warning: passing argument 1 of ‘h’ makes pointer from integer without a cast

(This is the behavior I observe with gcc 4.8.2)

How do parser writers deal with this situation?

It seems the classic pipeline Lexer -> Parser -> Semantic Checker -> ... does not work here.
