Fixed.

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.
