Are we really encountering a case where the C compiler accepts -Wshorten-64-to-32 but the C++ compiler doesn't, or *vice versa*?  Or are we encountering a case where *neither* compiler accepts it, but CMake isn't detecting that?


Neither compiler supports that option.
It's highly unlikely that this directory was previously used with a compiler that *did* support it (unless Fedora pushed out a compiler downgrade) but I suppose it is possible. 


I don't know. On my (32-bit) system, both compilers correctly report that
it is not supported. I'd need to see the cmake output on a system that has
this problem.
Unfortunately the evidence is all gone now. Maybe if I hit the problem again in the future...
