Several months ago I attempted to upgrade libffi 3.0.10 to 3.0.11. The change was reverted because the soname change in this version of the library broke the build environment. I would still like to get 3.0.11 in Fedora. I don't anticipate any future ABI-breaking changes, and 3.0.12 will include additional ports like Aarch64, which is likely of interest to some Fedora developers. How do we coordinate a rebuild for dependent packages? Also, I assume this will have to wait 'til F18 is out (fine by me), but I'd like to deal with it early in the F19 cycle.
