-# Guarantee all of the standard directory variables, even when used with
-# autoconf 2.59 (datarootdir wasn't supported until 2.59c, and runstatedir
-# in 2.70) or automake 1.9.6 (pkglibexecdir wasn't supported until 1.10b,
-# and runstatedir in 1.14.1).

- 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.

- 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.

- 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.
