Port problem PostgreSQL to WinNT/2000

Hello to all!
I have a Win2000 Advanced Server and I need to use PostgreSQL on it.
I downloaded PostgreSQL 7.1, Cygwin in full configuration and cygipc 1.09-2.
Then I do:

1. Install Cygwin, IPC, start IPC as service - ok. Set all environment as described in Cygwin, IPC and PostgreSQL documentation.
2. Compile PostgreSQL - ok.
3. Under bash start initdb:

Creating directory I:\cygwin\usr\local\pgsql\data
Creating directory I:\cygwin\usr\local\pgsql\data/base
Creating directory I:\cygwin\usr\local\pgsql\data/global
Creating directory I:\cygwin\usr\local\pgsql\data/pg_xlog
Creating template1 database in I:\cygwin\usr\local\pgsql\data/base/1

DEBUG: NextTransactionId: 514; NextOid: 16384
DEBUG: database system is in production state
ERROR: cannot create pg_proc: No such file or directory

initdb failed.
Removing I:\cygwin\usr\local\pgsql\data.
Removing temp file /tmp/initdb.2016.

What I can do with this?
Thanks.
