I have added a new interface in the version in development to get the
PACKAGE_VERSION and other PACKAGE* variables as set by configure:

my $texinfo_version = Texinfo::Common::get_constant('PACKAGE_AND_VERSION');

However, since you need to know the version to know if you can call that
function, this is probably be useful for you only when you do not
support versions older than the first version with that function anymore.
