Can't get postmaster to start :-(

Running:

  Win-2K
  cygwin     - 1.3.22-1
  postgresql - 7.3.3-1
  cygipc     - 1.14-1

Install process worked fine. No problem running cyg-ipc (as an
automatic service). But any attempt to:

postmaster -i -D /usr/share/postgresql/data &

fails with the following message:

IpcSemaphoreInitialize: semctl(id=2, 0, SETVAL, 0) failed: Invalid
argument
LOG:  startup process (pid 2472) exited with exit code 1
LOG:  aborting startup due to startup process failure

What have I forgotten to do :-( ??
