How can agreements be achieved about names for corresponding enumerations and type definitions?

Would you like to use any macros for consistent name generation?

The names should already have some shared prefix. If they don't, don't touch them. No macros needed.

Have you got any additional preferences about naming conventions for enumeration types?

Yes: do no change the names.

#define FOO_A 1
#define FOO_B 2

->

enum {
FOO_A = 1,
FOO_B = 2,
};

I do not want to change the value identifiers.
Do you really want to work with unnamed/anonymous enumerations?

Do you prefer any specific name selection (NVE) to enable the reuse of explicit data types?
