I understood that part. My statement is that BROKEN_GCC_WLOGICALOP will
not be defined if configure was run on a system with non-GCC compiler.
Unless I oversaw something fundamental ... which I will never rule out.

OTOH I am fine with any approach that let's me build on my back-level 
RHEL6 box for the time being. BTW: there's still a build/install issue
for non-systemd systems, see
