Yep, thats why.  I wanted avoid exactly that.  Having some code need to
know that function foobar() is only available with CONFIG_BAZ is set is
really ugly ...

The attached patch hides the magic in alternative.h and provides some
dummy inline functions for the UP case (gcc should manage to optimize
away these calls).  No changes in module.c.

cheers,
