Some functions/macros like isspace take an int and require the

argument to have the value of an unsigned char (or EOF). Under
Solaris, gcc complains when the argument is a char (as this is a
possible bug, on platforms where char is signed, like Solaris). The
attached patch fixes such problems (well, perhaps I've changed more
than necessary, but this doesn't hurt).
