Hi, Matthias.

I am not shure your approach will work. THREAD_LOCAL global vars become
initialized at thread start. We do not create threads. AlsoTHREAD_LOCAL
is defined in newer c versions. To stay portable as possible I prefer
avoiding newer c features.

But i am no c guru and i have nothing to decide in this project. All i
did is putting my fingers in a open wound.

I want to use libtcc from lua and i started the suggested work for my
private project already to learn about tcc internals and to keep going.
