No, I didn't before.  Looks like a good idea, except for the minor
cosmetic issue of having numerous exposed macros which do not belong
to the library interface.  Thanks for the suggestion, though, this
looks like the easiest and least error-prone solution.

BTW, current CVS autotools will break the example given in
ax_prefix_config_h.m4 unless obsolete AM_CONFIG_HEADER is replaced
with AC_CONFIG_HEADERS.

Still there is the Autoconf documentation issue with AC_DEFINE*,
namely that I would like to know if usage with 2 args is deprecated.
