Declaration prevents Visual Studio 2008 from auto-completing shared_ptr

[Edward Loper <edloper@…>]

A forward declaration for shared_ptr in boost/exception/exception.hpp confuses Visual Studio's Intellisense parser, preventing it from doing auto-completion for any boost::shared_ptr objects. This can be fixed by replacing "<class>" with "<class T>" in the forward declaration (as shown in the attached patch file).

Strictly speaking, this is not a bug in Boost, but in Visual Studio; but unless there's a good reason to use "<class>" in the forward declaration rather than "<class T>", this change would be very helpful to all Visual Studio users if you made this change.

VS 2010 can handle it fine.

True; but unfortunately my current development environment requires that I use Visual Studio 2008. And I'm sure I'm not the only one in that situation.
