Yeah, I had missed that. I assume this is being done with a linker script.

The new features of GCC4 are handy if you need to export multiple C++
classes, and you don't want to mention hundreds of mangled names in a linker
script (including vtables, etc.), or manually mark each and every member
function and member variable with a GCC-specific __attribute__. But this is
not the case here.
