          Description

          There is some inconsistency between
          MAKETIME(0,0, negative_integer_number) and
          MAKETIME(0,0, negative_decimal_number)

          SELECT MAKETIME(0,0,-1), MAKETIME(0, 0, -0.1);
+------------------+----------------------+
| MAKETIME(0,0,-1) | MAKETIME(0, 0, -0.1) |
+------------------+----------------------+
| NULL             | 00:00:00             |
+------------------+----------------------+

          The expression with the negative decimal number should also return NULL.

          MySQL-5.5 exhibits the same behaviour.
          MySQL-5.6 returns NULL for both expressions.
