10# autoconf 2.59 (datarootdir wasn't supported until 2.59c, and runstatedir
11# in 2.70) or automake 1.9.6 (pkglibexecdir wasn't supported until 1.10b,
12# and runstatedir in 1.14.1).

15  dnl Technically, datadir should default to datarootdir.  But if
16  dnl autoconf is too old to provide datarootdir, then reversing the
17  dnl definition is a reasonable compromise.  Only AC_SUBST a variable
18  dnl if it was not already defined earlier by autoconf.
