| 7 | dnl This file must be named something that sorts before all other | |
| 8 | dnl gnulib-provided .m4 files. It is needed until such time as we can | |

| 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. | |
