/* 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. */
