The main additional resource requirement is building libstdc++ in stage
1 (and stages 2 and 3 if you were previously not building the C++
compiler at all).  The C++ compiler proper is fairly small by
comparison.

At present you can use --disable-build-poststage1-with-cxx.  However, in
the future, I would like to change gcc to always build with C++.  Yes,
this will take more resources.
