/*
The declaration above exists specifically to make |nsCOMPtr<T>| _not_ compile with only
a forward declaration of |T|. This should prevent Windows and Mac engineers from
breaking Solaris and other compilers that naturally have this behavior. Thank
<law@netscape.com> for inventing this specific trick.
Of course, if you're using |nsCOMPtr| outside the scope of wanting to compile on
Solaris and old GCC, you probably want to remove the enum so you can exploit forward
declarations.
