OK, it is possible that there is an include order issue in hildonmm,
but it is quite difficult to tell without knowing the subtleties of
your build system, as that could equally well be the cause. Are you
able to post a Makefile so that I can test it?

You said that removing a hildonmm.h include got you further, but how
so? Do you still get the same issue with the SizeType define or is
there a different issue? You said that that was an include cycle, so
is there a missing include guard in hildonmm?
