John David Anglin <danglin at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|preprocessor |bootstrap --- 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.
