PATH_SEPARATOR in test/automated/Makefile.in

[Eli Zaretskii <eliz@gnu.org>]

This stuff is not working, and as a consequence the test suite
currently fails on MS-Windows with werdo error messages about failure
to load Lisp files.

The problem is that (a) @PATH_SEPARATOR@ is replaced with ':' (of
course: what else did you think MSYS Bash will use?), and (b) the
automatic replacement of ":." with ";." doesn't happen either, because
evidently the MSYS heuristics doesn't consider "." something that
cannot be anything but a file name, so it plays safe and leaves it
alone (":./" does work).

So the possibilities as I see them are:

 . Remove PATH_SEPARATOR and use -L "$(PATH_SEPARATOR)$(srcdir)/"
   (with a slash) instead of  -L "$(PATH_SEPARATOR)$(srcdir)"

 . Leave PATH_SEPARATOR, but set it to ';' "manually" for MinGW,
   instead of relying on $PATH_SEPARATOR computed in configure by
   asking Bash.

Meanwhile, to run the test suite on Windows, say

   make PATH_SEPARATOR=';'
