/* Apple engineering suggested using options align=power as a
workaround for a bug in OS X 10.4 (Tiger) that prevented ioctl(...,
SIOCGIFCONF, ...) from working properly in 64 bit mode on Power PC.
It turns out that the underlying issue is the size of struct
ifconf, which the kernel expects to be 12 and natural 64 bit
alignment would make 16. The same bug appears in 64 bit mode on
Intel macs, but align=power is a no-op there, so instead, use the
pack pragma to instruct the compiler to pack on 4 byte words, which
has the same effect as align=power for our needs and works on both
Intel and Power PC Macs. */
