  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 # - AC_CHECK decl, file, func, header, lib, member, prog, sizeof, type
  85 #   Performed in the semantics tests.
  86 # - AC_CONFIG
  87 #   They fail when the source does not exist.
  88 # - AC_INIT
  89 #   AC_INIT includes all the AC_INIT macros.  Note that there is an
  90 #   infinite m4 recursion if AC_INIT it used twice.
  91 # - AC_LANG*
  92 #   Heavily used by other macros.
  93 # - AC_PATH_PROGS?, AC_F77_FUNC
  94 #   They produce `= val' because $1, the variable used to store the result,
  95 #   is empty.
  96 # - AC_TRY, AC_.*_IFELSE, AC_RUN_LOG.
  97 #   Used in many places.
  98 # - _AC_
  99 #   Internal macros are used elsewhere.
 100 # - AC_OUTPUT
 101 #   Already tested by `AT_CHECK_MACRO'.
 102 # - AC_FD_CC
 103 #   Is a number.
 104 # - AC_PROG_CC, AC_C_(CONST|INLINE|VOLATILE), AC_PATH_XTRA
 105 #   Checked in semantics.
 106 # - AC_CYGWIN, AC_CYGWIN32, AC_EMXOS2, AC_MING32, AC_EXEEXT, AC_OBJEXT
 107 #   AU defined to nothing.
 108 # - AC_PATH_XTRA
 109 #   Checked in semantics.
 110 # - AC_SYS_RESTARTABLE_SYSCALLS, AC_FUNC_WAIT3
 111 #   Obsolete, checked in semantics.
