	* win32/win32.c (wrename): use MoveFileExW instead of MoveFileW,

	* win32/win32.c (setup_overlapped, finish_overlapped): extract from
	  rb_w32_read() and rb_w32_write().

	* win32/win32.c (setup_overlapped): check the error code in addition
	  to the result of SetFilePointer() to determine if an error occurred,
	  because INVALID_SET_FILE_POINTER is a valid value.

	* configure.in: check struct timeval exist or not.

	* include/ruby/missing.h (struct timeval): check HAVE_STRUCT_TIMEVAL
	  properly. and don't include sys/time.h if struct timeval exist.

	* file.c: include sys/time.h explicitly.

	* random.c: ditto.

	* include/ruby/missing.h (struct timespec): include <sys/time.h>

	* include/ruby/missing.h (__syscall): moved to...

	* io.c: here. because __syscall() is only used from io.c.

	* include/ruby/missing.h: move "#include <sys/type.h>" to ....

	* include/ruby/intern.h: here. because it was introduced for
	  fixing NFDBITS issue. [ruby-core:05179].

	* thread.c: disabled _FORTIFY_SOURCE for avoid to hit glibc bug.
	  [Bug #8080] [ruby-core:53349]

	* test/ruby/test_io.rb (TestIO#test_io_select_with_many_files):
	  test for the above.

	* include/ruby/missing.h: removed __linux__. it's unnecessary.

	* test/ruby/test_file_exhaustive.rb: add test to verify.

	* win32/file.c (replace_to_long_name): skip automatic path expansion
	  when wildcard character is used.  [ruby-core:49451] [Bug #7374]

	* test/ruby/test_file_exhaustive.rb: add a test for above.

	* win32/file.c (replace_to_long_name): skip expansion for all wildcard
	  characters.
	  [ruby-core:49451] [Bug #7374]

	* test/ruby/test_file_exhaustive.rb: add more assertions to test.

	* win32/file.c (replace_to_long_name): correct logic around wildcard
	  characters detection and ensure wide-chars are used as pattern.

* gc.c: Use the non-recursive marking instead of recursion. The
  recursion marking of CRuby needs checking stack overflow and the
  fail-safe system, but these systems not good at partial points,
  for example, marking deep tree structures. [ruby-dev:46184]
  [Feature #7095]

* configure.in (GC_MARK_STACKFRAME_WORD): removed. It's used by
  checking stack overflow of marking.

* win32/Makefile.sub (GC_MARK_STACKFRAME_WORD): ditto.

* gc.c (free_stack_chunks): it is used only when per-VM object space
  is enabled.

* gc.c (rb_objspace_call_finalizer): mark self-referencing finalizers
  before run finalizers, to fix SEGV from btest on 32bit.

* gc.c (gc_mark_stacked_objects): extract from gc_marks().

* gc.c (rb_objspace_call_finalizer): call gc_mark_stacked_objects
  at suitable point.

* gc.c (init_heap): call init_mark_stack before to allocate
  altstack. This change avoid the stack overflow at the signal
  handler on 32bit, but I don't understand reason... [Feature #7095]
