This fixes compilation on systems w/o any atomics implementation available,
e.g. MinGW32 < 4.0.
FWIW, atomics actually is available there, but those mingw builds target
i386 by default and the instructions necessary for the atomic stuff came
in 486. If you add -march=i486 or something similar (I've written some
notes about it in bugzilla somewhere iirc) it works just fine.
Nevertheless, handling this situation properly in configure sure is
welcome - didn't have a look at the patch itself right now though.
