dnl Provides the RRA_LIB_KRB5_OPTIONAL macro, which should be used if Kerberos
-dnl support is optional. This macro will still always set the substitution
-dnl variables, but they'll be empty unless --with-krb5 is given. Also,
-dnl HAVE_KERBEROS will be defined if --with-krb5 is given and
-dnl $rra_use_kerberos will be set to "true".
