problem with initdb in windows nt 4.0

hi everyone,

here is what happens when i try to run initdb after installing
postgresql under nt:

$>initdb –username=Postgres

We are initializing the database system with username Postgres
(uid=1005).
This user will own all the files and must also own the server process.

Creating Postgres database system directory d:\usr\local\pgsql\data

Creating Postgres database system directory d:\usr\local\pgsql\data/base

Creating template database in d:\usr\local\pgsql\data/base/template1
ERROR: mdopen: couldn't open d:\usr\local\pgsql\data/pg_variable: No
such file or directory
ERROR: mdopen: couldn't open d:\usr\local\pgsql\data/pg_variable: No
such file or directory
………………

and the last ERROR lines are repeated endlessly until i manually stop
the process. same thing if i try with another valid
username. the data, base, and template1 directories are created and also
the first two pg_* files in template1, but apparently it
stops because it cannot create pg_class. here is what i have in lib and
bin:

$>ls –ls /usr/local/pgsql/lib

when i installed postgresql, configure, make, and make install seemed to
execute without any serious incident, i sent their output to .log files
and checked them out with "cat *.log | grep Error" to make sure
everything went fine. i also checked the environment with
check_cygwin_setup.sh, the /etc/passwd file (local) was created.

may i ask three questions:

(1) why can't i run initdb?

(2) i have winnt 4.0 with service pack 6, cygwin-b20.1, and the
postgresql-6.5.3 sources; my gcc -v says version is 2.91.57
(egcs-1.1) : is there anythyng wrong with this configuration?

(3) why initdb --username=jkr, as indicated in the winnt install readme
and update post? why not just initdb --username=postgres; and, finally,

(4) are both the Cygwin32 IPC package by Ludovic LANGE and
cygwin32_ipc-1.03.tar.gz necessary? it seems to me that i
can start ipc-daemon without the latter package but maybe i'm wrong (or
maybe it's already there, from the cygwin installation,
and i don't know it).

thank you very much for any help you can provide.
