Yes.  There needs to be an include hack to add the missing declarations,
or they need to be added to os_defines.h.  The latter would fix the libstdc++
problem but isn't a general solution.  A user can always add his own
declarations as a workaround.  Libstdc++ won't build at all under hpux
10.20 without defining _SB_CTYPE_MACROS, so this can't be reverted.

With respect to the mainline bootstrap problem with "-Werror", the
reported "error" is only the first of probably several system header
generated problems under hpux.  This particular one is seems to be
a make work project because the compiler should be able to tell that
there is no difference between signed and unsigned in this case (i.e.,
"x & MASK", where MASK is a non-negative number less than INT_MAX).
