Browse Source 
SetHandleInformation.
	* fhandler_disk_file.cc (fhandler_disk_file::lock): Always use
	UnlockFileEx/LockFileEx functions.
	* net.cc (fdsock): Don't bother to duplicate socket for inheritance.
	* sysconf.cc (get_nproc_values): Take NT for granted.
	(get_avphys): Ditto.
	* syslog.cc (WIN95_EVENT_LOG_PATH): Remove define.
	(get_win95_event_log_path): Remove.
	(vsyslog): Fix formatting.  Take NT for granted.
