I saw that it now uses a BSD getopt. But it doesn't really matter, as
long as the getopt() implementation is POSIX-compliant. The autoconf test
will notice that getopt() works and not use the replacement. That's fine.

Regarding AH_TOP: I don't see warnings for it, except when I use
"autoconf -Wobsolete" or "autoconf -Wall", but with these flags I also
warnings about the use of deprecated macros inside autoconf itself. So
I figure I better shut off these warnings.

Regarding AH_BOTTOM: It's essential that this comes last in the config.h
file, because it includes public system header files. How do you specify
with AH_VERBATIM that a piece of code must be the last one?
