The problem was with the environment -- I assumed it was only the path.
The startup-script depends on CYGWIN_ROOT, which your installer set for
the current user (during install) only.

I don't know, whether or not KDEDIR and LTDL_LIBRARY_PATH are needed or set
by the startup-script, but I copied them to the machine environment anyhow.

For that user KDEHOME is set to "Application Data" in the Windows user
profile directory, which seems weird to me, but as far as I can see, the
startup-script overwrites this setting. I guess it should be removed.

Maybe your startup-script should be a bash-script instead of a batch-file
-- after a login you could use the variables set by the cygwin login script
(and assume defaults within the cygwin tree). That would be a better place
than the Windows environment.

I used it during kde startup -- glad that I've got 512 MB of RAM
-- filemon used well above 100 MB. :-)

Now I see how things are related. IMHO, you shouldn't use the Windows
environment at all, but use the cygwin profile (if needed) and a
bash-script.
Otherwise, the CYGWIN_ROOT variable should be sufficient, since all others
can be (are already?) set by the startup-script.

The startup-script could set the CYGWIN_ROOT to "C:\cygwin" if it's not set.

I just examined that script. If LTDL_LIBRARY_PATH is needed, you should
introduce a default for that, too. And I don't know, if you really want
to overwrite KDEHOME and SHELL, if they are already set.
