I'm sure this is a follow-up to this thread from January <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00514.html> You showed some code that uses SIOCSIFLLADDR. Maybe the problem is that this value does not fit in an 'int'? $ cat foo.c #include <sys/socket.h> #include <net/if.h> #include <sys/sockio.h> unsigned long x = SIOCSIFLLADDR; int y = SIOCSIFLLADDR; $ gcc -S -m64 foo.c $ cat foo.s .globl _x .data .align 3 _x: .quad 2149607740 .globl _y .align 2 _y: .long -2145359556 .subsections_via_symbols Does this patch fix the issue for you? 2011-02-22 Bruno Haible <br...@clisp.org> ioctl: Fix for MacOS X in 64-bit mode. * lib/ioctl.c (rpl_ioctl): Zero-extend, not sign-extend, the request value.
