--- Comment #6 from John David Anglin <danglin at gcc dot gnu.org> ---
I think this issue can be resolved by including <climits> instead of
<limits.h> in system.h when compiling with g++.
However, we currently assume gnu++98 in stage1 and long long support
was not added until c++11. r235550 introduced a long long variable
which isn't guarded by HAVE_LONG_LONG. So the change needs fixing.
