Summary: We are going to use some `C11` features, namely unnamed union fields. Sadly we still have to support gcc4.4, which does not support `-std=c11` while its `-std=gnu99` compiles the code but with the warning `ISO C doesn't support unnamed structs/unions`. This patch adds a feature test function to help detect compiler differences. Test Plan: ``` make local ``` Reviewers: #mercurial, ttung Reviewed By: ttung Subscribers: mjpieters Differential Revision: https://phabricator.intern.facebook.com/D3649021 Signature: t1:3649021:1470082430:bced7bd155eb60cc8c3e1c2d950092e2abd39a00
