--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think __GLIBCXX_BITSIZE_INT_N_? will always be 20, 24 or 128 right now and I
think really unlikely that it will be ever 1, after all, we have a perfect type
for that already, bool.  Except maybe for _BitInt(1) if it ever makes it into
C++.
