Thanks, but this doesn't seem like quite the right approach, as seen
by the fact that HAVE_ZLIB_H was dropped from config.h.in.  I think
you need to keep the AC_DEFINE out of the AC_CHECK_LIB.  I would guess
that it would work to just change the default case of AC_CHECK_LIB to
[;] or something similarly innocuous.
