[Christian JULLIEN]

Hi all,
with the last commit my simple test works and ...
BINGO! my huge OpenLisp non-regresion test suite which stress a C compiler a lot, has got 0 error (ZERO).

Congrat all! to me, tcc is now fully functional on RPi

Tonight, I'll make even more stress tests which can take hours if not days on RPi!
