Created attachment 200539 [details] Patch to link in libatomic on 32-bit archs with no 64-bit atomics devel/protobuf needs to link against libatomic for 64-bit atomics when built with ports gcc on platforms that don't have 64-bit atomic operations. The attached patch, obtained from upstream and massaged to fit our version, fixes this. The patch is already included in the next version of protobuf.
