 For software with problems like that all over the place, you could use
gcc -fsigned-char if you don't have time to track down the individual
bugs.  Char might be unsigned for a reason, like that it's faster to use
unsigned char on that arch, so the best solution is still to say signed char
where you mean it, use int with getchar, etc.
