The use of #ifndef seems to imply that this is a target macro, to be defined in libgcc_tm.h. In that case it should be documented, and poisoned in system.h under the "only used for code built for the target" case, and this: > +#if defined __x86_64 && !defined __LP64__ is inappropriate since you should instead put it in an appropriate header in libgcc/config/, rather than hardcoding an architecture-specific #if in an architecture-independent file. -- Joseph S.
