The strtoul() function that we used to parse many of the options accepts negative values, and silently wraps them to the equivalent unsigned values. For example, -1 becomes 0xFFFFFFFF, on platforms where unsigned long is 32 bits wide. Also, on platforms where "unsigned long" is 64 bits wide, we silently casted values larger than UINT32_MAX to the equivalent 32-bit value. Both of those behaviors seem undesirable, so tighten up the parsing to reject them.
