I was hoping for something where each include could just do the normal
thing:

#ifdef HAVE_CONFIG_H
#include <config.h>
#endif

I ended up with:

AH_TOP([#ifndef INCLUDED_CONFIG_H
#define INCLUDED_CONFIG_H])

AC_CONFIG_HEADERS([config.h],[echo "#endif /* INCLUDED_CONFIG_H */" >>
config.h])

Yes, if this preprocessor symbol shows up in another include file, I'm
screwed.  In my case that doesn't happen but I suppose some convention of
using the package name would be safer.

Thanks for your help.
