Right now, the following code will not compile for me:
typename aligned_storage < sizeof ( MyClass ) >::type storage;
this was formerly:
aligned_storage < sizeof ( MyClass ) > storage;
but I added the ::type after reading the above message.  Am I doing 
something wrong, or do I just need an up to date version of the library?

I am using VC 7.1 and get the error:
error C2039: 'MyClass' : is not a member of 'boost::aligned_storage<size_>'
