dnl ATHENA_UTIL_SS |

dnl Sets MOTIF_LIBS and defines HAVE_MOTIF if Motif used. |

dnl ATHENA_MOTIF_REQUIRED |

dnl Generates error if Motif not found. |

dnl ATHENA_AFS |

dnl AFS_LIBS will be set to that value if AFS is found. |

dnl ATHENA_AFS_REQUIRED |

dnl Generates error if AFS libraries not found. AFS_DIR |

dnl will be set to the prefix given. |

dnl ATHENA_KRB4 |

dnl Sets KRB4_LIBS and defines HAVE_KRB4 if krb4 used. |
||||
dnl ATHENA_KRB4_REQUIRED |
||||
dnl Generates error if krb4 not found. Sets KRB4_LIBS |
||||
dnl otherwise. (Special behavior because krb4 libraries |
||||
dnl may be different if using krb4 compatibility libraries |
||||
dnl from krb5.) |
||||
dnl ATHENA_KRB5 |
||||
dnl Sets KRB5_LIBS and defines HAVE_KRB5 if krb5 used. |
||||
dnl ATHENA_KRB5_REQUIRED |
||||
dnl Generates error if krb5 not found. |
||||
dnl ATHENA_HESIOD |
||||
dnl Sets HESIOD_LIBS and defines HAVE_HESIOD if Hesiod |
||||
dnl used. |
||||
dnl ATHENA_HESIOD_REQUIRED |
||||
dnl Generates error if Hesiod not found. |
||||
dnl ATHENA_ARES |
||||
dnl Sets ARES_LIBS and defines HAVE_ARES if libares |
||||
dnl used. |
||||
dnl ATHENA_ARES_REQUIRED |
||||
dnl Generates error if libares not found. |

dnl used. |

dnl ATHENA_ZEPHYR_REQUIRED |

dnl Generates error if zephyr not found. |

dnl compiler find the requested libraries. Put ATHENA_UTIL_COM_ERR |

dnl and ATHENA_UTIL_SS before ATHENA_AFS or ATHENA_AFS_REQUIRED; there |
