Fix type compatiblity of enums and ints

an enum must be compatible with one or more integer type, so adjust the test accordingly. That means the following redeclarations should work: enum e6 { E1 = -1, E0 }; void f3(enum e6); void f3(int); // should work as int and e6 are compatible while the following should not: void f4(enum e6 e); void f4(unsigned e); // should error as unsigned and e6 are incompatible
