Previously the g++ default was --std=gnu++98,

And when building gcc-4.9, stage1 does not override that with

That has changed, and that triggers the latent bug.
So just use -std=gnu++98 in STAGE1_CXXFLAGS or configure with
CXX='g++ -std=gnu++98' if you try to build gcc-4.9 with gcc 6?
I really don't think we should work around this in GCC 6.
I agree, but #undefining those macros doesn't hurt, and hopefully the
issue will go away.
