But just FYI: here are the lists of files from gcc49 that having /usr/include first will change what gcc49 sets up for itself and has been using in my past activities (spanning both 4.9.4/include/ and 4.9.4/include-fixed/ ): > #

All along I've been doing renaming in that area to allow buildworld/buildkernel use. This should be fine with my fix too. Trying add this to your make.conf for now: CFLAGS.gcc+= -isystem /usr/include -- Regards, Bryan Drewery
