# 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
+# and some are already tested elsewhere. AC_EXCLUDE_LIST must filter out
# the macros we don't want to test in ac-macros.at.

-# - AC_CHECK alignof, decl, file, func, header, lib, member, prog, sizeof,
-# host/target tool, type
-# Performed in the semantics tests.

-# 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 includes all the AC_INIT macros. Note that there is an
