b0c48d8e45 Oops; we need to make sure that DNS request names are matched in the _questions_ section of the replies. Rejecting answers whether the _answers_ section did not match made us reject A records waiting at the end of a CNAME record. Bug 823.

Try to compile with fewer warnings on irix64's MIPSpro compiler /
 environment, which apparently believes that:
   - off_t can be bigger than size_t.
   - only mean kids assign things they do not subsequently inspect.
 
 I don't try to fix the "error" that makes it say:
 
 cc-3970 cc: WARNING File = main.c, Line = 1277
   conversion from pointer to same-sized integral type (potential portability
           problem)
 
     uintptr_t sig = (uintptr_t)arg;
 
 Because really, what can you do about a compiler that claims to be c99
 but doesn't understand that void* x = NULL; uintptr_t y = (uintptr_t) x;
 is safe?
