clang vs gcc 4.7

[Luis Garcia Alanis]

Hi,

I was reading that clang had support for ObjectiveC 2.0 and gcc didn't. However I also read that as of gcc 4.6 it also supports ObjectiveC 2.0.

Is there a reason clang should be used? 

Etoile seems to require clang. This makes me thing clang still doing something that gcc cant.

Thanks

Luis
