PostgreSQL 7.3 under Windows/cygwin: initdb fails with error IpcSemaphoreCreate: semget ... failed: Function not implemented

Hi,

I have a serious problem installing PostgreSQL 7.3 on Windows.
I have an up-to-date cygwin installation under Windows2000 Server sp3,
installed the cygipc 1.11-1 package as instructed,
but I fail to initialize the database.

Querying www.boost.com and groups.boost.com was not much help, much
problems related to the error message
"IpcSemaphoreCreate: semget" "Function not implemented" do not relate to
Windows/cygwin, and I found nothing that helps to get ahead.

Here the steps taken:
