I haven't tried, but per the explanation, you get issues if you tried to
include bug.h in the first place, since then you get

bug.h
-> includes build_bug.h (since the patch)
-> uses build_bug.h from backports
-> includes bug.h (does nothing, double include)

and you're then missing the defines from build_bug.h.

I don't think so. However, I don't yet see why passing the version on
the command line doesn't work, since we only ever need to care about
files we compile?
