Gcc does have the problem; the title of the thread is misleading. See
later posts such as:
<http://lists.boost.org/Archives/boost/2005/08/92002.php>
and
<http://lists.boost.org/Archives/boost/2005/08/92004.php>

For now it is SFINAE cannot be safely, portably used upon anonymous
enums, though this could change, depending how we resolve core issue
488.
