Assorted GCC warnings, "make test" results from latest CVS

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

The top ChangeLog entry as of my "cvs up" is Andrey's 20872.

This is on RHEL3, trying again with unicode support defined.  I suspect most
of these are places where zlelineasstring()/stringaszleline() are needed:

Several of the tests start printing hashmarks where without the unicode
support they finish in less than 1 second, but that may be a red herring
because I don't see how the ZLE changes could be affecting anything but
the Y* tests.  Y01completion.ztst hangs, as do Y02 and Y03 if I force
them to run with TESTNUM=.  The other tests are (expectedly, I imagine)
all fine.
