Subject: [PATCH] Work around an AC_CHECK_LIB bug in Autoconf
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
AC_CHECK_LIB([ldap], [ldap_initialize], [], [...]) should not append -lldap to
LIBS variable because third AC_CHECK_LIB arugment is defined and
empty.
But broken autoconf-2.69-21.fc23 thinks empty is undefined and
defaults to implicit if-found action. That results into linking all
executables to ldap library and that is unnecessary.
