+# This is quite unpleasant.  It turns out that most header checking
+# macros call AC_INCLUDES_DEFAULT.  By default AC_INCLUDES_DEFAULT
+# implies AC_HEADER_STDC and a bunch of conditional includes.  But
+# these header checks are obsolete as the documentation for
+# AC_HEADER_STDC says.  Instead, define AC_INCLUDES_DEFAULT ourselves.
+# The list of headers below is the list from `(autoconf) Default
+# Includes' (filtered by hand for the modern ones rather than the
+# fallbacks).  We must include $1 because AC_INCLUDES_DEFAULT is
