Well, I do think that a *new* architecture should indeed add all of
those, but make the 'struct stat' for all of them be the same.
So then if people do the system call rewriting thing - or just do the
manual system call thing with
syscall(__NR_xyz, ...)
it is all available, but it ends up being all the same code.
Wouldn't that be lovely?
Of course, I also happen to think that "new architecture" and "32-bit"
is just crazy to begin with, so honestly, I don't even care. 32-bit
architectures aren't really relevant for any new development, and I
think we should just codify that.
And on 64-bit architectures, the standard 'stat' works fine.
