Why is this casting needed? |

Hello,
I have two classes, A, and B, each which have "initWithNumber:" methods.
I have another class, C, which accepts an instantiated A object in one
of its constructors. I compile the following 'code':
C *c = [[C alloc] initWithA: [[A alloc] initWithNumber: 5]];
The compiler gives me a warning saying that "initWithNumber:" has two
definitions: one in A, and one in B. If I cast the result of [ A alloc ]
to (A*), no error is reported:
C *c = [[C alloc] initWithA: [(A*)[ A alloc ] initWithNumber: 5]];
Is this a bug or a feature? If GNUstep is using my regular GCC, my GCC
version is 3.4.5. Thanks
Nate
