I don't know. I don't know what the C++ standard says on this matter (two structures of the same name in different compilation units). I want to ask around at work, we've got some guys who are really into cutting-edge C++ standard knowledge 
According to the standard, GCC was right. The standard dictates, in the so called "one definition rule", that a structure, if defined in multiple translation units, must be defined with exactly the same tokens. Otherwise it's an undefined behavior (so we were lucky that our RasPis didn't explode
