# gl_CONFIGMAKE_PREP
# ------------------
# Guarantee all of the standard directory variables, even when used with
# autoconf 2.59 (datarootdir wasn't supported until 2.59c) or automake
# 1.9.6 (pkglibexecdir wasn't supported until 1.10b.).
AC_DEFUN([gl_CONFIGMAKE_PREP],
[
dnl Technically, datadir should default to datarootdir. But if
dnl autoconf is too old to provide datarootdir, then reversing the
dnl definition is a reasonable compromise. Only AC_SUBST a variable
dnl if it was not already defined earlier by autoconf.
if test "x$datarootdir" = x; then
AC_SUBST([datarootdir], ['${datadir}'])
fi
dnl Copy the approach used in autoconf 2.60.
if test "x$docdir" = x; then
AC_SUBST([docdir], [m4_ifset([AC_PACKAGE_TARNAME],
['${datarootdir}/doc/${PACKAGE_TARNAME}'],
['${datarootdir}/doc/${PACKAGE}'])])
fi
dnl The remaining variables missing from autoconf 2.59 are easier.
if test "x$htmldir" = x; then
AC_SUBST([htmldir], ['${docdir}'])
fi
if test "x$dvidir" = x; then
AC_SUBST([dvidir], ['${docdir}'])
fi
if test "x$pdfdir" = x; then
AC_SUBST([pdfdir], ['${docdir}'])
fi
if test "x$psdir" = x; then
AC_SUBST([psdir], ['${docdir}'])
fi
if test "x$lispdir" = x; then
AC_SUBST([lispdir], ['${datarootdir}/emacs/site-lisp'])
fi
if test "x$localedir" = x; then
AC_SUBST([localedir], ['${datarootdir}/locale'])
fi
dnl Automake 1.9.6 only lacks pkglibexecdir; and since 1.11 merely
dnl provides it without AC_SUBST, this blind use of AC_SUBST is safe.
AC_SUBST([pkglibexecdir], ['${libexecdir}/${PACKAGE}'])
