1 | dnl We define the macro GLIBC_PROVIDES to do an AC_PROVIDE for each macro |
2 | dnl which appears in configure.in before the sysdep configure scripts are run. | |
3 | dnl Each sysdep configure.in does GLIBC_PROVIDES first, to avoid any | |
4 | dnl AC_REQUIREs or AC_BEFOREs duplicating their code. | |
