[I'm not the maintainer or anything, but..]
.. it would be nice if you could provide a patch against
a) tcctest.c
b) tcc fixing the bug you see (including lots of comments explaining
your reasoning) including caveats).

Nowadays, fabrice is not able to/not in the situation/moot to take care
of tcc as he may (or may not) like, so please help him stripping down the
time needed for tcc as best as you see fit.

Thank you,
Bernhard
