I've now rebuild from scratch multiple times and IWFM. Details?

I'm using uid 100003 currently and mine is 271K in size. Under the
assumption that uids are growing monotonically on NT systems, I guess
we'll have some time to think about a change. The bigger problem will
be to update all Cygwin packages quick enough so that the upgrade is
more or less smooth. As long as ssh and inetutils aren't rebuild,
this problem won't happen at all. Worse: People with uids > 64K will
be unable to login for no apparent reason (from the users perspective).
Btw., I just found that the wtmp/utmp handling in syscall.cc is still
using 32bit offsets. I guess we will find a few more of this quirks in
Cygwin until we can eventually release the next version...
