[OpenWalnut-Dev] duplicate class names

[Mario Hlawitschka]

Hi,

the compiler cannot check because the collision happens at runtime when loading the different libraries. It usually checks within the same library and reports errors there.
It should be the dynamic linker that checks, and they tend to be amazingly lazy... (and highly platform-dependent)
