dnl @synopsis AC_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION])
dnl
dnl This macro _AC_DEFINEs VARNAME to the expansion of the DIR
dnl variable, taking care of fixing up ${prefix} and such.
dnl
dnl Note that the 3 argument form is only supported with autoconf 2.13 and
dnl later (i.e. only where _AC_DEFINE supports 3 arguments).
dnl
dnl Examples:
dnl
dnl AC_DEFINE_DIR(DATADIR, datadir)
dnl AC_DEFINE_DIR(PROG_PATH, bindir, [Location of installed binaries])
dnl

test "x$prefix" = xNONE && prefix="$ac_default_prefix"

ifelse($3, ,
AC_DEFINE_UNQUOTED($1, "$ac_define_dir"),
AC_DEFINE_UNQUOTED($1, "$ac_define_dir", $3))
])
dnl @synopsis CHECK_ZLIB()
dnl
dnl This macro searches for an installed zlib library. If nothing was
dnl specified when calling configure, it searches first in /usr/local
dnl and then in /usr. If the --with-zlib=DIR is specified, it will try
dnl to find it in DIR/include/zlib.h and DIR/lib/libz.a. If
dnl --without-zlib is specified, the library is not searched at all.
dnl
dnl If either the header file (zlib.h) or the library (libz) is not
dnl found, the configuration exits on error, asking for a valid zlib
dnl installation directory or --without-zlib.
dnl
dnl The macro defines the symbol HAVE_LIBZ if the library is found. You
dnl should use autoheader to include a definition for this symbol in a
dnl config.h file. Sample usage in a C/C++ source is as follows:
dnl
dnl #ifdef HAVE_LIBZ
dnl #include <zlib.h>
dnl #endif /* HAVE_LIBZ */

dnl @synopsis AX_MAINTAINER_MODE_AUTO_SILENT
dnl
dnl Set autotools to error/sleep settings so that they are not run when
dnl being errornously triggered. Likewise make libtool-silent when
dnl libtool has been used.
dnl
dnl I am using the macro quite a lot since some automake versions had
dnl the tendency to try to rerun some autotools on a mere make even
dnl when not quite in --maintainer-mode. That is very annoying.
dnl Likewise, a user who installs from source does not want to see
dnl doubled compiler messages.
dnl
dnl I did not put an AC-REQUIRE(MAINTAINER_MODE) in here - should I?
