glad to help.

an alternative for the discerning power user is to install a recent version of gcc locally (eg 4.8), and build 7.6.3 with that! (or just repoint your ghc settings file to a locally built version of real gcc.)

yes, assuming we have the time (after all, it's all volunteer time), that is the plan.

Hi Carter,

Thanks for this heads up! Many of us here are cutting edge Mac users, and would have been bitten by this.

Darin and I plan to spend some time next month preparing an unofficial patched version of ghc 7.6 that should play nice with clang / xcode 5, though at such a time ghc 7.8 will be in RC status at the very least.

Can this be backported to the 7.6.3 tag and released as 7.6.4? It would be nice to not have to choose between running the latest xcode and the ability to test multiple GHC versions.

Cheers,
Adam
