Ah I see, I'm not to well versed in GDC yet so I'm not really 
sure what the implications of my "workaround" actually were.

The bug still exists though, if you try and compile GDC (4.7) on 
OSX then it won't compile (it complains about missing symbols in 
relation to _tls_data_array)

Does anyone have any ideas on how to fix this?
