I think you should rewrite your macro as:

AC_DEFUN([AC_CHECK_FUNC_PROTO],
     [AC_CACHE_CHECK([for $1 function prototype in $2], [ac_cv_have_$1_proto],
         [AC_EGREP_HEADER([$1], [$2],
             [ac_cv_have_$1_proto=yes],
             [ac_cv_have_$1_proto=no])
         ])
     if test $ac_cv_have_$1_proto = yes ; then
             ac_tr_func=HAVE_`echo $1 | tr
'abcdefghijklmnopqrstuvwxyz' 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'`_PROTO
         AC_DEFINE_UNQUOTED($ac_tr_func)
     fi
