My patch (against cygipc-1.13pre1) changes the following cygipc
functions to return ENOSYS instead of EACCES if ipc-daemon is not
running:

    msgctl()
    msgget()
    msgrcv()
    msgsnd()

    semctl()
    semget()
    semop()

    shmat()
    shmctl()
    shmget()
    shmdt()

Since I could only (easily) test semget() and shmget() under PostgreSQL,
I decided to write a simply test program, cygtest.cc, to exercise all of
my cygipc changes.

Attached are the following files:

    o cygipc-1.13pre1.patch: ENOSYS patch
    o cygipc-1.13pre1.ChangeLog: corresponding ChangeLog entry
    o cygtest.cc: test program
    o cygtest.out: test program output before patch
    o cygtest2.out: test program output after patch

Thanks,
Jason
