Browse Source 
(RtlOemStringToUnicodeString): Define.
	* ntdll.h (struct _RTL_USER_PROCESS_PARAMETERS): Define.
	(struct _PEB): Redefine with a bit of content.
	(RtlAnsiStringToUnicodeString): Declare.
	(RtlOemStringToUnicodeString): Declare.
	* path.cc: Include ntdll.h.
	(_upp): New global variable pointing to user process parameter block.
	(get_user_proc_parms): New static function to retrieve user process
	parameter block.
	(close_user_proc_parms_cwd_handle): New function to close handle to
	current working directory in user process parameter block.
	(cwdstuff::init): Drop redundant declaration of dynamically_loaded.
	Set current dir only on 9x.  Call close_user_proc_parms_cwd_handle
	on NT instead.
	(cwdstuff::keep_in_sync): Only on 9x.
	(cwdstuff::set): Keep behaviour on 9x.  On NT write cwd path into user
	process parameter block and set cwd handle to NULL.  Fix comments to
	reflect new behaviour.
