#At file:///bzrroot/server/mysql-5.1-innodb/ based on revid:jimmy.yang@stripped

 3679 Vasil Dimov	2011-01-07
      Fix Bug#59327 Fix autoconf usage for innodb_plugin
      
      AC_CHECK_FUNCS(f1 f2 f3, ACTION_IF_PRESENT)
      ACTION_IF_PRESENT is executed if any of f1, f2 or f3 is present.
      Fix this misusage, we want the action to be executed if all of the
      functions are present.
