            Bug ID: 90597
           Summary: xf86-video-intel trunk fails to build with gcc-5.
           Product: xorg
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/intel

I was hoping to see if an SNA problem with 2.99.917 had been fixed (will raise
that in a few days, after rebuilding a system with debug info), but it crapped
out.

This is with gcc-5.1.0 and a linux x86_64 system built with kernel 4.0.3
headers.
