Suggestion for Solaris

I see lots of people writing in with the IPC problem on the solaris
port.  May I suggest that  the configure program recognize when
someone's port is solaris and run some IPC checks (shmem and sem).  If
these fail (not enough shmem or too few sems), a message be printed
directing the user to a faq that gives instructions on how to :
(1) determine the required sizes and numbers
(2) change the /etc/system file to effect this
(3) reboot
(4) recover in case a mistake is made in (2)

Also, it is possible, for purposes of testing, to set -N (small number
of processes) and -B (N x 4 seems to be a good number even though the
default in the code is N * 2) in order to proceed with the build and the
regression testing.

I think there is a note somewhere in the documentation telling how to
reduce the hard-coded default number of backends (I forget exactly
where, but I found it once) but it does not say anything about raising
number of buffers, or where, or even why.  Since 6.5 allows number of
backends to be set at runtime, why not just go for the smaller number
hard-coded with lots of docs?
