: Yes, NetBSD has it:
: 
: #define TAILQ_FOREACH_SAFE(var, head, field, next)                      \
:         for ((var) = ((head)->tqh_first);                               \
:                 (var) != NULL && ((next) = TAILQ_NEXT(var, field), 1);  \
:                 (var) = (next))
: 
: Another option to this patch would be:
: 
: Renaming _SYS_QUEUE_H_ to QEMU_SYS_QUEUE_H_
: at least allows to include both sys-queue.h and <sys/queue.h>.

That would be the better option, because _XXX is reserved for the
compiler/library/toolchain, not for the application...
