I'll try that. 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/ ):

This should be fine with my fix too.

Trying add this to your make.conf for now:

CFLAGS.gcc+= -isystem /usr/include
