--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- 3d7c150e3f05 libstdc++-v3/config/os/bsd/freebsd/os_defines.h (Benjamin Kosnik 2003-07-05 04:05:45 +0000 39) #define _GLIBCXX_USE_C99_LONG_LONG_DYNAMIC (_GLIBCXX_USE_C99_DYNAMIC || !defined __LONG_LONG_SUPPORTED) has not changed in years. Maybe it was the recent `#pragma system_header` changes.
