error trying to port to windows 2000

hi i used the following link to help me port postgresql to Windows 2000

http://people.freebsd.org/~kevlo/postgres/portNT.html


I think all went well until i got to step 14: I get the following error...

administrator@PHOENIX /usr/local/pgsql/data
$ C:\cygwin\usr\local\pgsql\bin\postgres.exe: ***
recreate_mmaps_after_fork_failed
Startup failed - abort
NOTICE:  IpcMemoryDetach: shmdt(0x0x7190000): Invalid argument
NOTICE:  IpcMemoryDetach: shmdt(0x0x7060000): Invalid argument
NOTICE:  IpcMemoryDetach: shmdt(0x0x7050000): Invalid argument

any idea what i did wrong??

thanks
