i found a neat trick to do it with the C pre-processor after all.
this makes the enum definitions themselves arguably somewhat less
legible, but on the upside the build system becomes simpler, and IDEs
can build/update their code models without having to (re-)build the
project first.
somewhat as a side effect, this gives bit enums proper names, so we
don't need to refer to them by cryptic prefixes anymore.
