SubjectRe: High UID support for Linux
   Date: 	Fri, 20 Nov 1998 19:50:32 -0500 (EST)

Your real problems will be system calls. There isn't enough space in
some of the structs. Sign extension and trunctuation will cause great

The system call problem is easy; we simply create new system calls that
return new structures, and let glibc handle the problem of deciding
whether or not the new system calls are present. The structure which
glibc exports to the user applications fortunately already supports
32-bit uid's.

The only problem them would be for people using libc5 or a.out
libraries. They would simply not be able to take advantage of > 16bit
uids on their system.
