--- Comment #23 from Jonathan Gray <jsg at openbsd dot org> 2011-07-28 19:24:43 UTC --- yes, with the bypass line as proposed both #ifndef NULL #ifdef __GNUG__ #define NULL __null #else #define NULL ((void *)0) #endif #endif and #ifndef NULL #ifdef __GNUG__ #define NULL __null #elif defined(__cplusplus) #define NULL 0L #else #define NULL ((void *)0) #endif #endif are left unchanged. svn sources still won't bootstrap but that is another problem and mentioned in separate pr already.
