No, definitely not.  See:

    https://code.google.com/p/protobuf/issues/detail?id=488

    
https://code.google.com/p/protobuf/source/browse/trunk/src/google/protobuf/stubs/platform_macros.h#64

    
http://buildd.debian-ports.org/status/fetch.php?pkg=protobuf&arch=ppc64&ver=2.5.0-1&stamp=1382012315

protobuf will fail to build from source on architectures that are not
explicitly supported.  This causes major problems for Linux distros like
Debian and Red Hat, which have to support more than just the
architectures Google explicitly supports.  We end up having to patch
protobuf to add support for the missing architectures.

It would be much appreciated if the protobuf developers implemented a
fall back using the standardized atomics support available in newer
versions of gcc/clang.
