Subject: Re: [boost] [config] GCC symbol visibility across shared libraries

Here's a notable distinction between GCC's visibility attribute and MSVC's __declspec: The latter is accepted on forward declarations while the latter produces a warning[*] and is otherwise ignored. That is, for portability, BOOST_SYMBOL_EXPORT must be applied to a UDT definition and not to a declaration.
* foo.hpp:n: warning: type attributes are honored only at type definition
