I think the issue is that by default the trunk is build (stage 1) by the
system C compiler and the next stages (Stage 2 and 3) are build by the
just-build C++ compiler. Thus, the C++ compiler supports the latest C++
features and also the latest options.
If one now uses --disable-bootstrap, the system C++ compiler is used to
compile the first and last stage - but if the system C++ compiler is
slightly older, it might not support the newest compiler flags.
I am not sure how to best solve this issues for --disable-bootstrap.
Besides bootstrapping, you could use --disable-libitm or it might also
work to specify --disable-build-poststage1-with-cxx which also saves you
from building the C++ compiler if you don't want it.
