* child_info.h (CURR_CHILD_INFO_MAGIC): Update.
(class child_info_fork): Remove stacksize, add stackaddr and guardsize members. * dcrt0.cc (child_info_fork::alloc_stack_hard_way): Partial rewrite to regenerate the stack exactly as in the parent. (child_info_fork::alloc_stack): Set stackaddr to 0, rather than stacksize. (dll_crt0_1): Check for stackaddr before changing the stack addresses in the TEB. * fork.cc (frok::child): Check for stackaddr here. (frok::parent): Set ch.stackaddr and ch.guardsize if not called from the main thread. * init.cc (dll_entry): Replace pointer to NT_TIB with pointer to TEB. Fix incorrectly changed address test before removing _my_tls. Set StackLimit to NULL on Windows 2000. Explain why. * miscfuncs.cc (struct thread_wrapper_arg): Store stackbase rather than stacksize, store commitaddr, remove guardsize. Store all pointers as char * for easier address arithmetic. (thread_wrapper): Rewrite to remove OS stack before calling thread function. Add lots of comments to explain what we do. (CygwinCreateThread): Reserve our own stack in case we got no application stack. Add comments. * ntdll.h (struct _TEB): Extend defintion up to DeallocationStack member. * thread.cc (pthread_attr::pthread_attr): Use "(size_t) -1" rather then 0xffffffff. * wincap.h (wincaps::has_stack_size_param_is_a_reservation): New element. * wincap.cc: Implement above element throughout.
