Why give an explicit integer label to any of the values (except the starting value)? It seems to me that the point of an enum declaration is to guarantee unique values for each tag, but relying on having any specific value correspond to a given tag is dangerous. I would write it like this : enum { f_open = 0, f_input_closed, f_output_closed, f_output_buffered }; This seems to solve the insertion problem transparently, whether at the end or in the middle...

This is a pain to read and maintain. You should write them like this:
enum { f_open = 1<<0, f_input_closed = 1<<1, f_output_closed = 1<<2, f_output_buffered = 1<<3 };
I stole this idiom from John Maddock: http://tinyurl.com/4no5s. It's supposed to make insertion in the middle easier. I think it's the vector vs. list tradeoff.
