I don't think it has anything to do with syscalls. It's likely a
memory corruption or somesuch. The problem appears on 23.X with
optimized builds.

Specifically:

 - EMACS_22_BASE (-O2)             -- get_token_information => 1
 - trunk (-O2)                     -- get_token_information => 0
 - trunk (w32.c compiled with -O1) -- get_token_information => 1

I'm trying to pinpoint when was the problem introduced.
