9x systems also have these files, they should reside in ${WINBOOTDIR}.
You also omitted a file called 'networks'.

Attached are a new version of your script, as well as a diff with your
original version.

Note also that the links should probably use proper case for the path and
filenames, in case someone has CYGWIN=*check_case:strict*.  I'm not sure
how to do this properly (use [cmd /c "dir /b "`cygpath -w $file`], maybe?)

It took the computational power of three Commodore 64s to fly to the moon.
It takes a 486 to run Windows 95.  Something is wrong here. -- SC sig file
