Yes, but this isn't really the reason why people want a C API, and this isn't how the vast majority of the C API users use it. The `.def` solution here is (or any technique that rely on the preprocessor in general) is a net negative.

I'm not sure I understand the concern with maintenance here. The value come from the DWARF spec. If these value change, everything is broken and a couple of entry in an enum in a C API will be the least of our concerns.
