Signedness of char depends on the OS. If you want compatibility with C, and in particular, the standard C library, then you should use the OS default, which is obtained from flag_signed_char.

flag_signed_char can also be overriden by user options, but this is not the main reason for using it.

Did you try testing this on a system where "char" defaults to unsigned char? It is possible that the patch might work fine on a signed-char system, but fail on an unsigned-char system. No, I didn't. I can test in powerpc system if that is necessary. Since James
Morrison already stated that treelang should be C like, I don't think that such test is usefull.

Thanks you very much.
