It's a GCC extension [1] but Clang also supports it [2]. It actually seems to have made its way into a number of other compilers as well.
Portability's a subtle issue since most of the code we might discuss on this list relies on Apple-specific language features that only Clang or GCC supports anyway, but I agree it's good to be aware of that even if you do choose to use language extensions.
