Here the need is for a macro that returns 1 or 0 whether given
symbol is defined or not, exactly as explained in the comment above the
definition for config_enabled() which in itself has nothing to do with
config.

So maybe config_enabled() should be renamed to __is_defined() or
similar, and then config_enabled() or its replacement defined in termps
of it.
