# - 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
# They produce `= val' because $1, the variable used to store the result,
# is empty.
#
# - 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'.

# Is a number.

# Checked in semantics.

# - AC_PATH_XTRA
# Checked in semantics.
