I was only giving an example of a C code to run through tcc.

Yes, I have also realized this, so that TCC is not a toy for me to include
in MC, it's a fully justified feature that when added to the scripting
support of MC/MCEdit, will provide with a concrete gains.

I think that this is not a problem. If someone codes in C, then he can get
segfaults. However, it's possible to write a segfault-free C code, so with
