unable to initdb under cygwin

Hi all!
I'm having the same kind of trouble I read about a few posts in this
list, i.e. :... FATAL: shmat(id=3538944) failed: Invalid argument
with all that follows.
I cygchecked the system and got only one error (see below), which I
don't deem responsible for that. I tried cygrunsrv with worst results.
Started both cygserver and ipc-daemon2 with more or less the same error.
Here follows some information which might help the more knoledgeable
among you to understand better what is going on:
