* ntdll.h (struct _PEB): Add members accessed by the fast cwd method starting with Vista. (struct _KUSER_SHARED_DATA): Define with only the DismountCount. (RtlAllocateHeap): Declare. (RtlEnterCriticalSection): Declare. (RtlFreeHeap): Declare. (RtlLeaveCriticalSection): Declare. * path.cc (get_user_proc_parms): Remove. (struct _FAST_CWD): New structure. (fast_cwd_ptr): Define. (SharedUserData): Define. (peek32): Define. (find_fast_cwd_pointers): New function to find the global pointer to the current FAST_CWD structure. (copy_cwd_str): New helper function. (cwdstuff::override_win32_cwd): New method to set the Win32 CWD. (cwdstuff::init): Just call override_win32_cwd from here when started from native Win32 parent. (cwdstuff::set): Access Win32 CWD via PEB reference instead of using get_user_proc_parms function. Memorize old DismountCount before opening directory handle. Call override_win32_cwd to set up Win32 CWD. Be more verbose in comments. * wincap.h (wincaps::has_fast_cwd): New element. * wincap.cc: Implement has_fast_cwd element throughout.
