I think that these tests are broken--or at least not applicable on ARM.

Both tests basically do

  {
    char c = -1;
    int i = c;
  }

and char is unsigned on ARM, so i will NEVER contain a negative value (reason:
because of C integer promotion rules).

If those are from tcc, let's check whether they force signed char by compiler
option.

Yeah.  I like it!

What's the next step?  Should we merge this part to master?

After that, make tcc work?
