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. Ian
