Something that I have seen in FreeBSD headers was something like this:

struct {
int ___prefix_a;
int ___prefix_b;
int ___prefix_c;
#define a __prefix_a
#define b __prefix_b
#define c __prefix_c
} a;

IOW make a record with dummy names, and then use #defines to access them.

Costs a bit of error message clarity though (and C/C++ doesn't have that much of that already)
