merge from trunk (r27887-r27889)

* test/win32ole/test_folderitem2_invokeverb.rb (test_invokeverb): should use
  assert_equal instead of assert in such cases.

* test/dl/test_func.rb (test_sinf): sinf() doesn't exist in the standard of C.

* test/csv/test_interface.rb (test_write_hash): may need to set binary mode
  when converter is specified.
