No, I don't think so. The Fedora ghc build is pretty standard - it should be very close to the upstream defaults. >> It would be good to make Linux default to use system libffi anyway. : > I don't like having to do this, but it reduces our testing surface (we don't > want to have to test against N different versions of libffi). Ok, but recently libffi is not updated that often. (Fedora will have shipped 3.0.9 for 4 releases soon (and the previous 4 releases were with 3.0.5). I suspect other distros are similar.) > I'm quite happy for distros to build against their system libffi though, and > we should > make that easier.

A configure option to enable system libffi would be very good. Should I file an RFE for that?
