Let me say more Every MacOS system supports thread_local storage, from 10.4 Tiger PPC on up.
Up to now, the base thread_local specifier introduced in MacPorts 2.6 has worked beautifully. There is no reason to manually specifiy any compiler other than that command. There is no reason to disable thread_local on any systems. I'm happy to help out if you are having issues, as I enabled thread_local on most of those systems, and have intimate knowledge of how it works. Best, Ken
