# ------------
# Macros which must not be checked at all (not by ac-macros.at, nor
# au-macros.at).
# The trailing new line is meant.

# ac_exclude_list
# ---------------
# The test `ac-macros.at' tries to run all the macros of Autoconf to check
# for syntax problems, etc.  Not all the macros can be run without argument,
# and some are already tested elsewhere.  EGREP_EXCLUDE must filter out
# the macros we don't want to test in ac-macros.at.
#
# - AC_CANONICALIZE, AC_PREFIX_PROGRAM, AC_PREREQ
#   Need an argument.
#
# - AC_CHECK decl, file, func, header, lib, member, prog, sizeof, type
#   Performed in the semantics tests.
#
# - AC_CONFIG
#   They fail when the source does not exist.
#
# - AC_FUNC_GETLOADAVG, AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU
#   Require a file that is not shipped with Autoconf.  But it should.
#
# - AC_INIT
#   AC_INIT includes all the AC_INIT macros.  Note that there is an
#   infinite m4 recursion if AC_INIT it used twice.
#
# - AC_LANG*
#   Heavily used by other macros.
#
# - AC_PATH_PROGS?, AC_F77_FUNC, AC_FC_FUNC, AC_FC_SRCEXT
#   They produce `= val' because $1, the variable used to store the result,
#   is empty.
#
# - AC_FC_FREEFORM
#   Requires the current language to be Fortran, not C.
#
# - AC_TRY, AC_.*_IFELSE, AC_RUN_LOG.
#   Used in many places.
#
# - _AC_
#   Internal macros are used elsewhere.
#
# - AC_OUTPUT
#   Already tested by `AT_CHECK_MACRO'.
#
# - AC_FD_CC
#   Is a number.
#
# - AC_PROG_CC, AC_C_(CONST|INLINE|VOLATILE), AC_PATH_XTRA
#   Checked in semantics.
#
# - AC_CYGWIN, AC_CYGWIN32, AC_EMXOS2, AC_MING32, AC_EXEEXT, AC_OBJEXT
#   AU defined to nothing.
#
# - AC_PATH_XTRA
#   Checked in semantics.
#
# - AC_SYS_RESTARTABLE_SYSCALLS, AC_FUNC_WAIT3
#   Obsolete, checked in semantics.
