bug#14944: 24.3.50; Cygw32 build break

[Kazuhiro Ito <kzhr@d1.dion.ne.jp>]

Because make_save_ptr is not defined in Cygw32, Cygw32 can't be built
on trunk.

(snip)
w32fns.o: In function `w32_monitor_enum':
/build/emacs/trunk/src/w32fns.c:4933: undefined reference to `make_save_ptr'
collect2: error: ld returned 1 exit status
(snip)


make_save_ptr is defined as below in src/alloc.c

#if defined HAVE_NS || defined DOS_NT
Lisp_Object
make_save_ptr (void *a)
{
  Lisp_Object val = allocate_misc (Lisp_Misc_Save_Value);
  struct Lisp_Save_Value *p = XSAVE_VALUE (val);
  p->save_type = SAVE_POINTER;
  p->data[0].pointer = a;
  return val;
}
#endif
