public headers not compatible with LVVM GCC 4.2

[ahlongxp]

Obviously LVVM GCC 4.2 doesn't know "strong" or "weak". This makes it impossible to use gh-unit for LVVM GCC 4.2.
I undersand the whole project is using ARC and thus clang is required.
I think a rewrite on the public headers(along with it's corresponding implementation files and -fno-objc-arc flags on them) should make gh-unit work with LVVM GCC 4.2 too. @gabriel , what do you think? Will you help on this?
Thanks very much!

I don't think we want to support llvm gcc... Maybe you can try using an earlier release? Sorry :)
