Build issue (compilation failure) if you have multiple includes of
hmm.h through different headers is the most obvious issue. So it
will be very obvious with any big driver that include the file in
different headers.

I can respin with that. Sorry again for not being more explanatory
it is always hard for me to figure what is not obvious to others.

Jï¿½rï¿½me
