Sometimes, a conditional-define symbol (which is what ".config" basically is) must be included to get correct compilation.

If it compiles cleanly, you need to go back and recompile the whole thing:

1. Make a nice, safe backup copy of ".config." (Oh, you did that already, didn't you?)
2. Rename ".config" to (say) "foobar," because the next step will wipe it out...
3. make distclean
4. Rename "foobar" back to ".config" (notice the dot).
5. make etc...

You must do this so that you do not "mix apples and oranges," with usually-fatal results. All kernel components must be compiled using exactly the same set of options.

Incidentally, no matter how much I "trust" the folks who prepare my (Gentoo...) distro, this is how I always compile a new kernel. I back up the old config, run make newconfig and the like, then back up the new config and perform the same (make distclean) process above. This guarantees that there is no "residue," and that everything is recompiled at the same time.
