My initial trial code seems reasonably promising, but this approach
does introduce the limitation that (without special precautions) we
can't use AC_DEFINE(GUILE_DEBUG ...) *and* expect to use GUILE_DEBUG
in our public header -- the two definitions, the one in config.h and
the one in libguile/scmconfig.h, would conflict.
The solution I'm leaning toward is to just remove the AC_DEFINEs for
any values we want to make public. That's probably OK since we have
to duplicate the AC_DEFINE information in the AC_CONFIG_COMMANDS when
generating scmconfig.h anyway. However, this does mean that if there
are any symbols that configure.in automatically AC_DEFINEs that we
also want to make public, we'll have to choose another name for the
public incarnation.
