Silence tautological comparison warnings Because "char" may be signed or unsigned depending on the system, comparing for byte values 128...255 has to be forced as an unsigned comparison to be portable and clear. Modify two such comparisons in the symbol handling code to treat the symbol offset as a pointer to unsigned. This quiets tautological comparison warnings on systems with an 8 bit signed type as the default char type.
