etc_changed, passwd & group.

["Pierre A. Humblet" <Pierre dot Humblet at ieee dot org>]

Chris,

Here is the code as it stands. It compiles & runs, and passes
fork tests correctly. Feel free to takeover or at least
have a look. I will continue testing tomorrow evening.

I include only the 5 files that are related to etc_changed,
the 5 others (setuid on Win9X) can wait.

Pierre

P.S. Does GetFileInformationByHandle () work reliably on network drives
(sse MSDN warnings)? If so, in pwdgrp.h read () it could replace 
GetFileSize and GetFileTime and one could also verify that the file hasn't
mutated into a directory.
