Oh, indeed: These were the so-called "PowerPC G5" machines. [1] But Gnulib has never been tested on such machines. It has been tested on "ibook G4" hardware and on x86_64 machines with CC="gcc -arch ppc". Therefore we don't know, and probably will never know, how to write correct, working code for Mac OS X 10.5 / powerpc64. (Such hardware was very expensive at the time [2] and is museumware by now.)
