struct ipc_perm and size of seq member

[Franz Sirl]

Hi,

I'm finally able to run 2.4.0-t8 on my B&W G3 and can now track down the 
remaining problems with glibc-2.1.9x. With 2.4 I still have an IPC problem, 
that maybe related to different notion of the size of seq. 2.4 on PPC 
defines it as 'unsigned long', but glibc-2.1.94 uses it as 'unsigned 
short'. Besides the missing padding in powerpc/bits/ipc.h, why does glibc 
use a 16bit type here, while the kernel uses 32bit? Is this required for 
userspace compatibility?

Franz.
