I came >< this close to removing the assumed struct many years ago
when I orthogonalized sys/queue.h, but were persuaded by others that
it was pointless and that nobody were ever going to use it with C++
anyway, C++ being so much more evolved in such aspects :-)
Wouldn't
#ifndef SYS_QUEUE_STRUCT
# define SYS_QUEUE_STRUCT struct
#endif
Make more sense ?
That would allow C code to also make the struct explicit.

Never attribute to malice what can adequately be explained by incompetence.
