-// Normally we don't export class templates (but do complete specializations),
-// inline functions, and classes with only inline member functions. Exporting
-// classes that inherit from non-exported/imported bases (e.g., std::string)
-// will end up badly. The only known workarounds are to not inherit or to not
-// export. Also, MinGW GCC doesn't like seeing non-exported function being
-// used before their inline definition. The workaround is to reorder code. In
-// the end it's all trial and error.
