Committed to mainline and 4_2-branch.

As regards 4_1-branch, the bug is latent, because, as noticed by 
Andreas, in that branch we have the more serious issue that the 
atomic_word.h tailored at powerpc, alpha and ia64 are mistakenly not 
used, instead just the generic one. Thus, I mean to commit there also 
the below additional hunk.

Paolo.
