Fix TestArrayTypes on Windows.

Whether or not frames print their tid in hex or decimal is apparently
hardcoded to depend on the operating system.  For now a comment was
added that this should be changed to a more sane check (for example
a setting), and the OS check is updated to do the right thing for
Windows.
