I'm glad to hear that.

Mmm. Google said me that gcc 4.9 does so. I'm using 4.8.5 so I
haven't see the warning.
https://gcc.gnu.org/gcc-4.9/porting_to.html
1436: else if (HeadMatches2("CREATE", "SCHEMA") &&
1437: SHIFT_TO_LAST1("CREATE") &&
1438: false) {} /* FALL THROUGH */

expanding the macros the lines at the error will be
else if (HeadMatches2("CREATE", "SCHEMA") && (head_shift += find_last_index_of("CREATE", previous_words,
previous_words_count), true) && false) {} /* FALL THROUGH */
But the right hand value (true) is actually "used" in the
expression (even though not effective). Perhaps (true && false)
was potimized as false and the true is regarded to be unused?
That's stupid.. Using functions instead of macros seems to solve
this but they needed to be wraped by macros as
additional_kw_query(). That's a pain..
Any thougts?

Yes. It can be saved only by adding completion for every word,
as some of the similar completion is doing.

Thanks.
