This is my currect patch to get "make check" to pass iconvdata under
ia64. I have no idea what this patch

2000-09-03  Bruno Haible  <haible@clisp.cons.org>

	* iconv/gconv_dl.c (do_release_shlib): Don't decrement the counter
	below -TRIES_BEFORE_UNLOAD-1, to avoid wraparound.

is supposed to fix. It looks completely bogus to me. The only place it
gets decremented is

	assert (obj->counter > 0);
	--obj->counter;

Even if it gets decremented by some magic, its logic looks very strange
to me. Bruno, do you have a testcase for your patch? I'd like to see it
myself.

BTW, it also passed "make check" under ia32.

Thanks.
