32bit uids on Alpha, MIPS, PPC and Sparc64

[Andreas Jaeger <aj at suse dot de>]

AFAIK the Linux ports for Alpha, MIPS, PPC and Sparc64 always had
32bit uids and therefore don't need any compatibility stuff.

The following five files in sysdeps/unix/sysv/linux use __ASSUME_32BITUIDS:

getresgid.c, getresuid.c, msgctl.c, semctl.c, shmctl.c

Looking at the code from e.g. getresuid.c, I don't think this will
work with Alpha etc.  Jakub, does it work for you on Ultrasparc with
headers from 2.3.39+ kernels and --enable-kernel=2.3.40?  I would be
surprised ;-)

What's the best way to handle this?

I would like to move getresgid and getresuid to the i386 subdir and
have files in the generic linux dir that don't use __ASSUME_32BITUIDS.
The alternative would be to have files in the alpha etc subdirs with
do this right.

Do we have to change msgctl, semctl and shmctl, also?  Looking at the
code, I do think they're ok.

What do you think?  Shall I send a patch?
