initdb and IpcMemoryCreate

Have been using cywin postgres for a couple of years. Yesterday, I
upgraded to 7.1.3 of Postgres. Fired up ipc-daemon and then the following:

bash-2.05b$ initdb -D /pg_data -d -n
Running with debug mode on.
Running with noclean mode on. Mistakes will not be cleaned up.

initdb variables:
PGDATA=/pg_data
datadir=/usr/share/postgresql
PGPATH=/usr/bin
ENCODING=
ENCODINGID=0
POSTGRES_SUPERUSERNAME=Administrator
POSTGRES_BKI=/usr/share/postgresql/postgres.bki
POSTGRES_DESCR=/usr/share/postgresql/postgres.description
POSTGRESQL_CONF_SAMPLE=/usr/share/postgresql/postgresql.conf.sample
PG_HBA_SAMPLE=/usr/share/postgresql/pg_hba.conf.sample
PG_IDENT_SAMPLE=/usr/share/postgresql/pg_ident.conf.sample
The files belonging to this database system will be owned by user
"Administrator
".
This user must also own the server process.

The database cluster will be initialized with locale C.

but nothing for how to do that on Windows. Please help!!!
