The patch in comment 24 solves some of the problem. Thanks!
The error now is:

Just to be clear, as this bug report is quite misleading: once the initial

The first atomic.ii is from the failing revision 180821. The second one is
from the successful revision 180770 before the libgcc changes.

Actually, my previous successful bootstrap was for rev 180770. I happened to
catch you in the middle of your checkins, but before the libgcc changes.

Okay, I will try. I think that something about the reorganization is causing a
C header file to be interpreted as a C++ header. Something missing extern "C".

The failure is config/gthr-posix.h is not found in the search path when
building libstdc++ during bootstrap.
Paolo's suggestion probably was not well thought through.
