Re: [Qemu-devel] qemu-coroutine.c: error: thread-local storage not supported for this target

The lack of emulated TLS on 10.6 is the consequence of a political choice, though. GCC 4.3 was released long before Snow Leopard, but users are stuck with 4.2.1 because of the license.

Apple's not providing it on 10.6.x because 10.6.x is obsolete
as far as Apple is concerned. Supported versions of OSX use
clang, which has support for __thread. Missing __thread
support is an "old platform" thing, not a political GPL thing.
