Why is this a problem in the C++ bootstrap and not the normal one ?

I thought that adding --disable-werror would bring us further, but as it 
turns out - not by much:

http://gcc.gnu.org/ml/gcc-testresults/2011-05/msg01224.html says:

I have to see if it is useful to keep on testing the C++ bootstrap 
daily, because apparently, some bitrot already set in ...
