Cygwin PostgreSQL postmaster problem

Hi,

I'm trying to execute PostgreSQL on Windows 2000, but I have some problems
with it.

My config :

cygwin-1.1.8
cygipc-1.09-2
postgresql-7.1-beta5

I have successfully installed cygipc (ipc-daemon as a service) compiled
PostgreSQL and executed initdb.
But each time I try to execute postmaster, I get :

$ postmaster -i -d1
FindExec: searching PATH ...
FindExec: found "/usr/local/pgsql/bin/postmaster" using PATH
C:\cygwin\usr\local\pgsql\bin\postgres.exe: ***
recreate_mmaps_after_fork_failed
postmaster: reaping dead processes...
postmaster: Startup proc 1196 exited with status 256 - abort

Any Ideas ?

Thanks in advance !
