Yes, things used to be like that. I don't think
they are anymore, though. At Solaris, and DEC UNIX
there are variables in kernel (not #defines anymore),
and at DEC UNIX 4.0 there are even ways to enforce
minimum value to be higher than the default 5 for
use on system running binaries with low values in
the listen() limit.
On Solaris there seems to be runtime config parameter:
though what value it has now, I haven't tried to find out.

Yes, you can get it :-)
