I would bet these are because our custom Autoconf macros
(gcc/aclocal.m4 - no, that's not a generated file, unlike some) are
still coded to the 2.13 spec, which didn't really do C++. Rip out
those you can (many have been superseded by macros included in
autoconf 2.5x base), recode those that can't in preferred 2.5x idiom,
and things should be better.
