* win32/win32.c, include/ruby/win32.h (rb_w32_io_cancelable_p): renamed
from rb_w32_has_cancel_io(). now it takes a parameter as fd to check
the fd is console or not, because we cannot cancel console input even
if we have cancel_io function.
* io.c (WAIT_FD_IN_WIN32): call above function instead of the old one,
so now we can kill the thread which calls STDIN.gets.
the problem was reported by ko1 via IRC.
