Cygwin PostgreSQL DLL PATH (regression test) Problem

While running the regression tests, I have been bitten twice (once with
7.0.2 and once with a pre-7.1 Beta 2 snapshot) since pq.dll is *not*
in my PATH. The attached patch corrects this problem and obviates the
need for users to add "/usr/local/pgsql/lib" to their PATH.

I'm not sure if my patch is the best way to solve this problem. Note
that I'm "lucky" that plpgsql.dll doesn't end up in "/usr/local/pgsql/bin"
too. Also note that I don't like duplicating the .dll files and would
prefer to use symlinks. But, if I do that, then the real files must be in
bin and not lib due to Windows (i.e., not Cygwin) needing to load them as
DLLs.

Any feedback would be greatly appreciated.

Thanks,
Jason
