| # ------------------ |
| # 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}']) |

| 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. |

| 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. |
