11 # AC_DEFUN_ONCE([NAME], VALUE)

12 # ----------------------------

13 # Define NAME to expand to VALUE on the first use (whether by direct

14 # expansion, or by AC_REQUIRE), and to nothing on all subsequent uses.

15 # Avoid bugs in AC_REQUIRE in Autoconf 2.63 and earlier. This

16 # definition is slower than the version in Autoconf 2.64, because it

17 # can only use interfaces that existed since 2.59; but it achieves the

18 # same effect. Quoting is necessary to avoid confusing Automake.
