Win98SE_Postgres' initb FATAL shmat(id=1179648)


Can't manage initializing db in Postgresql-7-4-3;, Win 98se, Cygwin 1.5.10-3
I added " set CYGWIN=server" in cygwin.bat, and also added
"set PATH =C:\Programmi\GNU\CygWin\bin C:\Programmi\GNU\CygWIn\usr\slib\cygserver.exe:$PATH"


This is what I type at prompt:

$ cd C:/Programmi/Gnu/Cygwin/usr/sbin
$ start cygserver //server starts, in another shell
$ initdb -D /data //Ok here's the prompt: answer:
The files belonging to this database system will bw owned by user "admin".This user must own the server process.
The database cluster will be initialized with locale C.

Invalid argument


initdb: failed

// I tried to reduce the amount of shared memory making changes in cygserver-config, for example setting number of buffers to a lower value, no way; setting "kern.srv.sharedmem" to"no"doesn't work, program gets a number of SIGNAL 12 and initdb fails.)
//I saw that other people posted this problem in M-Lists, also googled about, found no valid answers.
Thanks for your attenction.
