>Header files are one of the things I miss the most about languages that aren't C. Having a very clear distinction between public and private, and interface and implementation is one of my favourite things about C code (at least the way I write it).

You don't need header files for that.

A dead simple to write tool that parses the actual non-duplicating info, files, and prints you the interfaces and access qualifiers for each method as such, presenting you everything or just the public ones etc, should suffice.
