* cygheap.h (cwdstuff::override_win32_cwd): Declare.
* 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.
