How to enable "shorthand" access element in NSArray

[Rael Bauer]

Hi,

I am using GNUStep on Windows with the clang compiler.

From what I have read, I should be able to access NSArray elements with 
following ("universal"...) notation

myArray[index]

instead of the expanded:  [myArray objectAtIndex:1]

However, when I try the shorthand, I receive an error message from the 
compiler:

e.g.

    NSArray * myArray = @[@"A", @"B", @"C"];
    NSLog(myArray[1]);

error:
 passing 'NSArray' to parameter of incompatible type 'id'

Is there something special I need to do to enable this notation? 
(compile flag?) (Is it a problem on Windows?)

Thanks
Rael
