10 | # autoconf 2.59 (datarootdir wasn't supported until 2.59c) or automake | |

14 | 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. | |
22 | if test "x$docdir" = x; then | |
23 | AC_SUBST([docdir], [m4_ifset([AC_PACKAGE_TARNAME], | |
24 | ['${datarootdir}/doc/${PACKAGE_TARNAME}'], | |
25 | ['${datarootdir}/doc/${PACKAGE}'])]) | |

27 | dnl The remaining variables missing from autoconf 2.59 are easier. | |
28 | if test "x$htmldir" = x; then | |

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. | |
