    NOTE:  These macros MUST be named UNUSED (exactly) or something
    prefixed with USED_IF_, or DEFUN docstrings will be parsed incorrectly.
    See comments in make_docfile.c (write_c_args).  You'd think that this
    wouldn't happen, but unfortunately we do indeed have some arguments
    of DEFUNs unused for GNU compatibility or because features are missing.

+   #### At one time, __attribute__ ((unused)) confused G++.  We don't know
+   which versions.  Please report problems and fix conditionals.
+   #### A similar issue arose with the Intel CC.  We know that v7 didn't
+   work and v9 does.  Let us know if v8 works or not, please.
+   See <m34plsmh88.fsf at jerrypc.cs.usu.edu>.
