Comment (by eschnett):

 _GNU_SOURCE has other effects as well, and may create all sorts of
 problems e.g. with <math.h> or <stdlib.h>. We can try, but it could lead
 to a rat's tail of problems on the usual weird architectures (AIX, PGI/IBM
 compilers, non-x86 CPUs, etc.).

 Since this is an architecture specific piece of code, I suggest instead to
 #define _GNU_SOURCE before including these include files, but in such a
 way that only this source file is affected. If necessary, we can add this
 #define also to the autoconf macros.
