Patch: bug fix in iconv finalizer

[Tom Tromey]

I'm committing the appended patch.  It fixes a stupid bug pointed out
to me by Andrew.

2000-02-09  Tom Tromey  <tromey@cygnus.com>

	* gnu/gcj/convert/natIconv.cc (Input_iconv::finalize): Call
	iconv_close when handle is not NULL.  Thanks to Andrew Haley.
	(Output_iconv::finalize): Likewise.
