dnl Technically, datadir should default to datarootdir. But if
15
dnl autoconf is too old to provide datarootdir, then reversing the
16
dnl definition is a reasonable compromise. Only AC_SUBST a variable
17
dnl if it was not already defined earlier by autoconf.
18
if test "x$datarootdir" = x; then
19
AC_SUBST([datarootdir], ['${datadir}'])
21
dnl Copy the approach used in autoconf 2.60.

if test "x$docdir" = x; then

AC_SUBST([docdir], [m4_ifset([AC_PACKAGE_TARNAME],
24
['${datarootdir}/doc/${PACKAGE_TARNAME}'],
25
['${datarootdir}/doc/${PACKAGE}'])])
27
dnl The remaining variables missing from autoconf 2.59 are easier.

if test "x$localedir" = x; then
44
AC_SUBST([localedir], ['${datarootdir}/locale'])
47
dnl Automake 1.9.6 only lacks pkglibexecdir; and since 1.11 merely
48
dnl provides it without AC_SUBST, this blind use of AC_SUBST is safe.
