It's interesting that the warning only popped on the one case where the
"/* looping version */" is on a separate line, not on the #else line.

Am cc'ing Joe Perches for that question. Joe - to get you up to speed,
checkpatch was run against drivers/staging/skein/skein_block.c, and it
flagged one definition of the macro R256, but not the other one, or the
two definitions each for R512 and R1024.  Any idea why?

Yup, that was it...
