Cygwin: postgres.exe exits with "*** recreate_mmaps_after_fork_failed" message

(Note that this bug might be considered a duplicate of #188).

I have installed PostgreSQL v7.1 on a system running Windows 2000
Service Pack 1 with a recent Cygwin installation. I have followed the
installation instructions to the letter, both in INSTALL and
doc/FAQ_MSWIN. ./configure, make, make install and initdb work fine.
Then I try to execute the following command:

/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data >logfile 2>&1 &

Per the instructions in INSTALL. postmaster.exe is loaded in the
background, as expected. Approximately one second later, I get the
following error message:

$ C:UtilityCygWinusrlocalpgsqlbinpostgres.exe: ***
recreate_mmaps_after_fork_failed

Note that I haven't done anything unusual; I have followed the
installation instructions to the letter, as mentioned.

For your reference, this bug has been filed as bug #305.

Best regards,
