I've slightly altered this such that we now don't need ++.o versions. This was achieved by adding:
#ifdef __cplusplus
extern "C" {
#endif

After we've ran the above conditional typedef compilation and:
#ifdef __cplusplus
}
#endif
At the end of eb.h
This means we don't have to duplicate dependancies for these files in the
makefile, thus reducing the possibility for build problems later.

Thanks for doing this, it'll certainly make things easier.

I'm not too sure I mind this that much.
At the end of the day it's not that bad and we shouldn't really have any
conflicting types etc which'd make this a problem.
A common.h would potentially be nicer though.

Cheers,
Adam.
