Really? You want to rewrite it entirely? Took me so much time and it work well 
now :( Couldn't just some CONFIG_TCC_ALLOCA macro be defined in Makefile when 
compiling?

Anyway, however you code VLA, you need alloca and need a way to detect if 
alloca is available or not. Do you have suggestion on how to rewrite it?
