Correct. But foo.gir files aren't made by people, they're made by g-ir-scanner.

g-ir-scanner isn't creating the name attribute from the #defines. The question is, what hint (i.e. annotation) to I pass to g-ir-scanner to get it to do the right thing?

I have done some experiments using the latest git.

adapting the annottion.h, the only ones that are generated are those in the namespace and with types from the namespace. hope this helps.
