I don't get it.  The script (what script?!?) should be updated to use
cygpath on the value read from the file, e.g. dldir=$(cygpath -f
/etc/setup/last-cache), just like any script that reads a key from the
registry or some program's .ini settings file or whatever.  The fact
that setup.exe happens to store its internal settings as a win32 path is
an internal detail, the file was never meant to be read by anything
else.  Besides, setup.exe is not a Cygwin app so storing its settings as
posix paths would just be extra hassle.
