To clarify, the problem occured because the C and C++ front-ends differ with regard to -Wmissing-prototypes (the C++ FE doesn't have it). People building stage2/3 in C++ mode won't see the error (but will see a warning in stage1), but people building in proper C mode (--disable-build-poststage1-with-cxx) will see the error.
