I had to do this check slightly different, otherwise GCC doesn't like it. :-(

 
 
 static uintptr_t ReadLong(char* buffer, intptr_t* position, int base) {
   char* end_address = buffer + *position;
   uintptr_t result = strtoul(buffer + *position, &end_address, base);
   CHECK(result != ULONG_MAX || errno != ERANGE);
   CHECK(end_address > buffer + *position);
   *position = end_address - buffer;
   return result;
 }
