Weird, Fedora 13 is still shipping 1.2.3, too. It's probably safest to
have the fallback for random old hosts anyway. Something like:
PKG_CHECK_MODULES([ZLIB], [zlib], [],
[AC_CHECK_HEADERS([zlib.h], [],
[AC_MSG_FAILURE([zlib.h is required to compile libfontenc])])
AC_CHECK_LIB(z, gzclose, [ZLIB_LIBS="-lz"],
[AC_MSG_FAILURE([zlib.h is required to compile libfontenc])])])
