File conflicts are detected and reported by libzypp/libsov; zypper just 
visualizes them.

On Fedora it's important that libsolv was built passing "-DFEDORA=1" to cmake. 
This will set the solver option 'implicitobsoleteusescolors=1', which enables 
support for installing multilib RPM package in parallel. (you can grep for 
implicitobsoleteusescolors in /var/log/zypper.log to check it's value).

If the reported conflicts are nevertheless wrong, you should file an issue at 

(Somehow related to https://github.com/openSUSE/libzypp/issues/46; zypper is 
not familiar with Fedoras way of installing multilib RPM package in

Of course. Preferred via github.
