dnl We don't want to have the full list of automatic defines from automake,
dnl and take care of the one we want explicit AC_DEFINE_UNQUOTED.
dnl While we do care about portability we get a long list of false-positives
dnl because of code-coverage parts that are only part of the final Makefile if we
dnl actually do use GNU make, so skip those warnings here and manually check with
dnl "automake -Wall" before creating a release quality tarball.
