I assumed an executable linked against boost.

I could reply to this in terms of content, but this is easier: what
you're saying by that is that declspec(thread)/... make no sense on
platforms that don't support delay-loading with static TSS, and
was/will never be used.
that's obviously not the case.
right now boost offers a platform independent interface to
TlsAlloc/..., but not to declspec(thread)/...
