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. |
