Yes, I know it does provide that, and I've used it a lot in the past.
A while ago I needed a linked list for another project where I needed
to be independent of FreeBSD. So I rolled my own (with a similar api)
and I've used it ever since. (It can be used both as a stack and queue).

It's not exactly rocket-science and it does increase portability since
this is a userland application.
If there aren't any major objections or other selling points in favor
for sys/queue.h (in a userland application!) I'm just going to leave
it as it is.
