WebIt made sense at the time for the compiler to treat simple char s as unsigned, whereas on the x86 simple char s are, by default, treated as signed. One workaround for users of GCC is to use the -fsigned-char command line switch or --signed -chars for RVCT, that forces all char s to become signed, but a better practice is to write portable code by declaring char …
