on the Power architecture seems to like having _unsigned_ chars by
default (unlike all other integer types, which, if not explicitly
marked 'unsigned' will be signed). This messes with a couple of the
tables of constants. The solution is either to force the compiler to
used signed chars by default, or to explicitly change the structures
such that the members are explicitly signed. Dan actually fixed this
within a day of me reporting the bug to him, but I forgot to report
back here. His webpage has been updated to document this gcc-gotcha.
