Well, of course the user _has_ to dig into the code and check if the
feature is supported, because there is no information what the
"#undef" or the comment means - it can mean anything:

- disabled here and left in so you can easily re-add it if you like
- disabled because known to be unsupported or broken
- disabled because untested
- ...

Please provide one working configuration, or several config options,
but don't try to add kind of configuration menues using "#define" /
"#undef" lists. These are useless and confusing at best.
