I ran across this before with 4.8.0 when we were getting ready to
bring 4.8.1 into the build system:

I was reading threads and it had to do with -fpermissive. Any input?
Has anyone encountered this in their multilib builds? One other use
has mentioned at the IRC channel. They said it compiled weird but
worked. Not sure what that means.
Sincerely,
