* include/ruby/win32.h (FD_SET): change function to macro.
To avoid buffer overflow when smaller FD_SETSISE is used in ext
libraries.
* win32/win32.c (rb_w32_fdset): this function is not used anymore.
But we leave this for compatibility.
* win32/win32.c (rb_w32_select_with_thread): fix SEGV when smaller
FD_SETSISE is used in ext libraries. Dereference of fd_set pointer
causes SEGV.
* test/-ext-/win32/test_fd_setsize.rb(TestFdSetSize): add tests for
above.
* ext/-test-/win32/fd_setsize/depend: ditto.
* ext/-test-/win32/fd_setsize/extconf.rb: ditto.
* ext/-test-/win32/fd_setsize/fd_setsize.c: ditto.
