Hi,

I'm a developper of the OSCAR Cluster opensource software and I4m in the process of integrating naemon in se supported things that can be configured from the cluster install wizard.

For that, I'm integrating naemon into the oscar build system and while it works fin on fedora-20, it fails to build on centos-6 with the following errors.
(the build command is: rpmbuild -bb naemon-0.8.0.tar.gz)

...

# everything seems ok and then:

Can this be fixed for next release? (either by disabling -Werror on centos6 or by fixing the warning by not ignoring the return code).

Best regards.
