+void f() throw(int);
+// Pointer to function with spec
+void (*fp)() throw (int);
+// Function taking reference to function with spec
+void g(void pfa() throw(int));

+typedef int (*pf)() throw(int); // xpected-error spec-on-typedef

+// Some more:
+// Function returning function with spec
+void (*h())() throw(int);
+// Ultimate parser thrill: function with spec returning function with spec and
+// taking pointer to function with spec.
+// The actual function throws int, the return type double, the argument float.
