In most ports of FreeBSD parts to Linux that I've seen, the preferred
solution has to been to bring the entire FreeBSD queue.h with you rather
than relying on the native Linux queue.h. This is what we do for OpenBSM,
for example; this also helps out when you get to Mac OS X, Solaris, etc,
where all the queue.h's continue to vary in subtle ways. This depends a
fair amount on a lack of header pollution in the OS's own include files, of
course...
Fortunately, in Solaris where I am testing the import of sys/cdefs.h and
sys/queue.h today, things seem to be `ok'. Just importing the two headers
at http://hg.hellug.gr/bmake/gker/rev/68bfc25ed443 seems to have moved
things one step closer towards building everything on Solaris:
Now off to the next little annoyance. Building with Sun Studio on Solaris
10, in my test machine at home, stops at:

The next part, about the missing errx() functions on Solaris is going to be
tonight's fun. If there are too many missing functions, it may be worth
adding a static `libcompat' with copies of just the functions we need to run
BSD make on non-BSD hosts.
It's beginning to sound like it would be really nice to have an
autoconf'd/automake'd version of our make to drop onto Linux, Solaris, etc,
etc, systems in order to bootstrap our compile. I share Warner's reluctance
to add autoconf parts to our native build, but having 'bsdmake' as a starting
point is useful, and would put those other platforms more at parity with Mac
OS X as a starting point (probably ahead due to more accessible native build
tools). I'm a bit surprised there isn't already a Linux 'bsdmake' package
floating around...
(When I say 'nice' above, I mean it in the normal autoconf sense of the word
'nice', so don't take that the wrong way!)
