merge revision(s) 24993:24997,25069:25074:
* win32/win32.c (rb_w32_select): wait specified time on select.
* win32/win32.c (rb_w32_select): on 1.8, we don't need to poll sockets,
because our select is never called from multiple threads.
* instruby.rb: win32/win32.h exists in srcdir.
reported by arton ( http://www.artonx.org/diary/20090919.html#p01 )
* win32/win32.c (subtract): if the parameters are same value, should
return zero.
* win32/win32.c (rb_w32_select): of course, need to initialize rest.
