I don't find this (nor the autoconf check) particularly likely to be
helpful. The most likely way the flag would unintentionally be added would be
via the cflags of some dependency - which won't be picked up by the tests.
However we do have tests during the builds that should pick it up, in date.c
and timestamp.c...
