It might be better to have config.h do something like this:

#define CONFIG_H

Warning: Quite a few misbehaving packages actually install their config.h.

It might be better to have an autoconf macro, e.g.:
  AC_GUARD_CONFIG_H([MYPFX])

that adds multi-inclusion guards and prefixes the generated #define names.
I'm redirecting to that list.
