Understand that it's not formally supported in C's syntax specification, but
curiously nor is the definition of struct { :3; }, although the text seems
to implies it defines a struct containing an 3-bit unnamed (and unspecified)
integer type?

So by implication would typedef struct { BF_3:3 } be required syntactically
to define a 3-bit (unspecifed) bit-field type which may then be used to
subsequently declare a named member: struct { BF_3 x; } ?
