I thought about that too, but writing those params into g_once makes the
code more readable. 

Another problem, that I just noticed is, that we can't use GOnce for
g_static_mutex_get_mutex_impl, because that would we a chicken/egg
problem, but we can use the same technique and the same configure.in
tests.

Bye,
