But using "array[]" means that "sizeof()" no longer works, and then you 
have to use "offsetof()", which is a big pain.

I think all relevant compilers end up accepting [0] (probably giving a
warning, especially in some pedantic mode), since it's been how gcc users
have been doing things for years (gcc was late to the [] syntax).
