There's no need to mark a function as inline in the function declaration. In fact, it causes a compilation error:

The last time I compiled libvirt-cim this wasn't an issue! Additionally my daily Coverity builds libvirt-cim from upstream from scratch without issue...
So is this from a 'newer' compiler? I have:
$ gcc --version gcc (GCC) 4.9.2 20150212 (Red Hat 4.9.2-6) Copyright (C) 2014 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
I'm not disagreeing this is a problem and needs to be fixed...

This happens only on fedora-rawhide where is a new gcc that almost fully supports the new c99 standard and that standard is a default one on that gcc version. $ gcc --version gcc (GCC) 5.0.0 20150407 (Red Hat 5.0.0-0.22)
FWIW:
libvirt-cim patches have been sent to the libvirt-cim list @libvirt-cim@redhat.com and not libvir-list...
