Strange thing is that "make test" fails, while "prove -b" passes.

The PERL_UNUSED_RESULT macro was added into perl in v5.21.0-35-gffea512 and v5.20.0-79-g9182835 commits. That explains why it fails on perl < 5.20.1.

Unfortunatelly not. See <http://matrix.cpantesters.org/?dist=threads+1.98>. The updated ppport.h still does not supply PERL_UNUSED_RESULT definition. Even latest Devel-PPPort-3.30 does not know the PERL_UNUSED_RESULT. -- Petr

Really fixed, now. (I'm pretty sure.)
