problem with ipc-daemon2 start as a service

Hi,

I've build from sources postgresql 7.4.1 with the same ./configure command as described in this guide:

http://www.tishler.net/jason/software/postgresql/postgresql-7.4.1.README

This is what I get whenever I try to launch ipc-daemon2:

cray(at)lavieenrose ~
$ cygrunsrv -S ipc-daemon2
cygrunsrv: Error starting a service: QueryServiceStatus: Win32 error 1062:

I have already tryed to do the chmod thing, changed nothing.
Also I don't have any logs in /var/log/

But if I don't use ipc-daemon2 as a service then when I run step 8 I get this:
<log>

postgres(at)lavieenrose /usr/share/postgresql
$ initdb -D ./data/
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale C.

DETAIL: Failed system call was shmget(key=1, size=1081344, 03600).
HINT: This error usually means that PostgreSQL's request for a shared memory se
gment exceeded available memory or swap space. To reduce the request size (curre
ntly 1081344 bytes), reduce PostgreSQL's shared_buffers parameter (currently 50)
and/or its max_connections parameter (currently 10).
The PostgreSQL documentation contains more information about shared memo
ry configuration.
