Once again Bison has a bug, so -Wswitch-default can not be used
by default.

And traded for a fewer number of same.

No tradeoffs.

Only if available.

'b' and 'r' options can never work as they aare not in ALL_OPTIONS.

The broadcast options removed a while ago.

-Wformat-nonliteral complains about a feaature ntpd uses a lot.
-Wmissing-declarations now on by default.

Formerly it was set by compiler name.

This used to work...

Merge commit.
