Hi John,

Thanks for your reply. My reading of the code is that it does indeed
work correctly if char is unsigned - it just ends up making some
comparisons which resolve to compile-time constants, which generates
warnings if GCC is given the right flags. The patch you linked looks
like it should fix the problem, though I have not tested it. In the
short term I am looking into removing the -funsigned-char flag from
our builds, since AFAICT it is not necessary.

Thanks again,
