From 7460bfd32bd2680383c72d7d26ccb7776ccffb00 Mon Sep 17 00:00:00 2001
From: Corinna Vinschen <corinna@vinschen.de>

Subject: 	* cygerrno.h (__seterrno_from_nt_status): Define. Always set
 Win32 	error code as well as errno. Use throughout where errno is set from 
 NT status. 	(set_errno): Evaluate val only once. 	*
 fhandler_disk_file.cc (fhandler_base::fstat_by_handle): Fix typo in 	debug
 output. 	* fhandler_mem.cc (fhandler_dev_mem::open): Rely on 
 __seterrno_from_nt_status setting Win32 error code in debug output. 	*
 fhandler_proc.cc (format_proc_uptime): Ditto. 	(format_proc_stat): Ditto. 
 * fhandler_process.cc (format_process_stat): Ditto. 	* sysconf.cc
 (sysconf): Ditto.
