for an explanation of the nature of the problem, see: http://sources.redhat.com/automake/automake.html#index-underquoted-_0040code_007bAC_005fDEFUN_007d-232 "Starting with Automake 1.8, aclocal will warn about all underquoted calls to AC_DEFUN. We realize this will annoy a lot of people, because aclocal was not so strict in the past and many third party macros are underquoted; and we have to apologize for this temporary inconvenience." a solution generally involves changing: AC_DEFUN(AX_FOOBAR, [ ... ]) to AC_DEFUN([AX_FOOBAR], [ ... ]) (note the added brackets around AX_FOOBAR.)
