It's claimed to be 8 times faster than gcc -O0 ;-)

All programs produced by SmartEiffel compile with latest tcc release (including 
itself of course). Fabrice kindly fixed all bugs who occured with SmartEiffel C 
generated code. It's wonderful and the best is to use SmartEiffel -no_split 
flag because tcc is so fast ! Of course, according to such performance, I added 
tcc as supported target for SmartEiffel compiler some release ago ;-)

Best Regards to all,
