Yes, slight problem there.  It checks regardless of whether the preceding
check succeeded or not.

dnl Test for libz
AC_CHECK_LIB(z, inflate,
  AC_CHECK_HEADER(zlib.h,
    Z_LIBS="-lz";  AC_DEFINE(HAVE_LIBZ)))
AC_CHECK_LIB(z, compress, , 
   AC_MSG_ERROR([[

Let's try this instead (also fixing a typo in the message, sigh):

AC_CHECK_LIB(z, inflate,
  AC_CHECK_HEADER(zlib.h,[[
    AC_CHECK_LIB(z, compress,
      Z_LIBS="-lz";  AC_DEFINE(HAVE_LIBZ)),
      AC_MSG_ERROR([[
*** Incorrect libz version found.  Please make sure you do not have
*** an outdated libz.a or libz.so hiding in your X11 distribution or
*** elsewhere on your system.  Versions of libz with the "compress" and
*** "uncompress" symbols are sufficiently recent to build GNOME.]])]]))
