initdb problems

I read the FAQ about PostgreSQL on Cygwin, but I couldn't understand
where and when should I run:

# make MAX_CONNECTIONS=3D5 check

And how to increase SEMMNS to avoid the following failure:

DETAIL:  Failed system call was semget(1, 17, 03600).
HINT:  This error does *not* mean that you have run out of disk space.
        It occurs when either the system limit for the maximum number of se=
mapho
re sets (SEMMNI), or the system wide maximum number of semaphores (SEMMNS),=
 woul
d be exceeded.  You need to raise the respective kernel parameter.  Alterna=
tivel
y, reduce PostgreSQL's consumption of semaphores by reducing its max_connec=
tions
 parameter (currently 10).
        The PostgreSQL documentation contains more information about config=
uring
 your system for PostgreSQL.

I've just upgraded my Cygwin installation. The previous installation
of Cygwin + PostgreSQL had no problems at all.
