It was just to make sure that __declspec is really the only way to get
TLS on iOS.  And not, for example, the case when both __thread and
__declspec(thread) are supported, with the latter being just officially
preferred or something like this. You commit message for a similar
patch in xserver mentioned silencing warnings. And this got me confused.

If there are no objections and nobody suggests a better patch within a
few days, I guess we can just apply:
