Reconfiguring changes the makefiles. You should always clean after a reconfigure. That's true for the vast majority of software projects that use a makefile-creating build process.

If it's not possible to enable an algorithm, it isn't actually "supported", is it?

If Configure claims a particular algorithm can be enabled, then if it's not actually possible to build with it enabled and use it, I'd say that's a bug somewhere. I haven't tried to build with all possible Configure options enabled, though.
