  75 # ac_exclude_list
  76 # ---------------
  77 # The test `ac-macros.at' tries to run all the macros of Autoconf to check
  78 # for syntax problems, etc.  Not all the macros can be run without argument,
  79 # and some are already tested elsewhere.  EGREP_EXCLUDE must filter out
  80 # the macros we don't want to test in ac-macros.at.
  81 #
  82 # - AC_CANONICALIZE, AC_PREFIX_PROGRAM, AC_PREREQ
  83 #   Need an argument.
  84 #
  85 # - AC_CHECK decl, file, func, header, lib, member, prog, sizeof, type
  86 #   Performed in the semantics tests.
  87 #
  88 # - AC_CONFIG
  89 #   They fail when the source does not exist.
  90 #
  91 # - AC_FUNC_GETLOADAVG, AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU
  92 #   Require a file that is not shipped with Autoconf.  But it should.
  93 #
  94 # - AC_INIT
  95 #   AC_INIT includes all the AC_INIT macros.  Note that there is an
  96 #   infinite m4 recursion if AC_INIT it used twice.
  97 #
  98 # - AC_LANG*
  99 #   Heavily used by other macros.
 100 #
 101 # - AC_PATH_PROGS?, AC_F77_FUNC, AC_FC_FUNC, AC_FC_SRCEXT
 102 #   They produce `= val' because $1, the variable used to store the result,
 103 #   is empty.
 104 #
 105 # - AC_FC_FREEFORM
 106 #   Requires the current language to be Fortran, not C.
 107 #
 108 # - AC_TRY, AC_.*_IFELSE, AC_RUN_LOG.
 109 #   Used in many places.
 110 #
 111 # - _AC_
 112 #   Internal macros are used elsewhere.
 113 #
 114 # - AC_OUTPUT
 115 #   Already tested by `AT_CHECK_MACRO'.
 116 #
 117 # - AC_FD_CC
 118 #   Is a number.
 119 #
 120 # - AC_PROG_CC, AC_C_(CONST|INLINE|VOLATILE), AC_PATH_XTRA
 121 #   Checked in semantics.
 122 #
 123 # - AC_CYGWIN, AC_CYGWIN32, AC_EMXOS2, AC_MING32, AC_EXEEXT, AC_OBJEXT
 124 #   AU defined to nothing.
 125 #
 126 # - AC_PATH_XTRA
 127 #   Checked in semantics.
 128 #
 129 # - AC_SYS_RESTARTABLE_SYSCALLS, AC_FUNC_WAIT3
 130 #   Obsolete, checked in semantics.
