I've looked at how Windows does thread variables, so if you want to do
_Thread_local (which would presumably be based on the code for static
variables), then I can help out with (at least) the Win32 version (I
don't have an x86-64, and haven't seen anyone mention if Windows makes
any changes there). I MIGHT be able to actually do a Win32 version
myself, but I don't understand TCC enough to be certain of it (and I
don't have a clue how to add keywords).

An extended TCC (eTCC) compiler might be nice (some people have
suggested adding some sort of support for objects, which combined with
your tracked structures would be similar to Vala, and I myself intend
to finish a pet language & add an interface to TCC once I finish
debugging my tree implementation...), but such a project should be
separate from the TCC C compiler in the same way that the TCC
assembler is.
