If a class is exported,  its member functions also get exported. For 
non-member function, this must also be added. Structs and classes are roughly 
the same in C++ (different initialisation) but unless they include functions 
(not function pointers), the do not need to be exported (you don't link to 
it).

BTW: With gcc >= 4 on linux, you may also want to use
#define MYLIB_EXPORT __attribute__((visibility("default")))
and compile with -fvisibility=hidden. That allows to not export symbols for 
internal classes and it's faster at runtime.
