1285 – Exception typedefs not distinguished by catch

typedef Exception A;
typedef Exception B;
void main() {
 try {
 throw new A("test");
 }
 catch (B) {
 // this shouldn't happen, but does
 }
 catch (A) {
 // this ought to happen?
 }
}
Note, however, that dmd doesn't complain that the first catch masks the second, unlike when I write "catch (Exception) {...} catch (A) {...}." Something's up!

Fixed DMD 1.018 and DMD 2.002
