Well, that's the ugly part.  I had to munge glibc's sys/acct.h to reflect the
same changes as well to get the gnu tools to read the file correctly (the
accounting file does need to be started fresh with this struct, btw).

Here's the problem:  the kernel uses 32 bit uids internally, but external code
would default to 16 bit due to the ifdefs.

Unfortunately, I don't how else to support accounting with high uids.  All it
takes is two lines each in two files (linux/acct.h & sys/acct.h) to get
everything to work correctly.

So, what's the consensus:  are we going to leave accounting broken for high
uids, or support only low uids?  If I can get a patch accepted by the glibc
maintainers as well this will work for everyone.

I actually use high uids, so this is production issue for me.  :-P
