Can ipc-daemon2 put its files in directory other than /tmp?

[David Garamond]

I'm trying to bundle postgresql + cygwin in a single distribution for my 
clients. The goal is that a user can just extract the .zip file and run 
postgresql there (ipc-daemon2 + pg_ctl start; initdb need not be done 
because a zipped 'virgin' data dir will also be provided). Target 
platforms are Win98SE and WinXP Pro. The target machines do not have 
Cygwin installed.

It's pretty simple to do that. I just put all the files under 
postgresql-7.4.1\bin\, including many Cygwin DLLs, several needed 
commands like grep, basename, cat, chmod, sed, etc. And of course, 
postgres.exe, postmaster.exe (which I copied from postgres.exe; 
originally it was a symlink to postgres), and ipc-daemon2.exe.

However, ipc-daemon2.exe seems to always look for /tmp (which is 
c:\cygwin\tmp). On Win98, it seems to be able to use c:\tmp if 
c:\cygwin\tmp doesn't exist, but on WinXP Pro it can't.

Rather than creating c:\cygwin\tmp, can I make ipc-daemon2 put 
MultiFileMsg* and MultiFileShm* in some other place?
