How different is this from the previous situation? As I understand it
previously A_defcompiler would be linked against the system libstdc++
and B_gnuish would be linked against the gccXX port libstdc++. In my
experience libstdc++ does not have good ABI stability between versions
so shouldn't you have the same potential for problems?
