It is, but (pthread_once_t){0,0} is a different thing.
And the issue is that while

can work with PTHREAD_ONCE_INIT being defined to {0,0},
once = PTHREAD_ONCE_INIT
cannot work, even without pedantic. So we really have to keep
(pthread_once_t) in PTHREAD_ONCE_INIT for the dynamic initialization
case.
That being said, it's *really* odd that the package builds with
-Werror=pedantic. Each time gcc gets upgraded to a new version, it will
get new build failures... We'd probably to disable that in the Debian
build.
