Those macros are required by the ABI (C extension or full ABI) of each
of those targets.
What macro does tinyCC define for x86_64? or rather the target it is
being compiled for?
Maybe it should have been __x86_64__ instead of the current __x86_64 .

line of which file? Because I can't figure it out.

I can only find __thread in one place:
gprofng/libcollector/heaptrace.c which I suspect could be changed to
_Thread_local since C11 is common enough.

Thanks,
Andrew
