Anyway, I could use an education about why there isn't a guard against
multiple inclusion built in to autoheader, as well as a way to add one
myself.  AH_TOP puts the first part where I want, but I've got multiple

last in the file.

"config.h" may be provided from multiple packages at once and all included instances may be required. The user that includes it needs to manage proper use.
