    The attached script reports C functions not flexed by unittests. It
    needs a 'coverage' build and a run of the tests. Coverage data is then
    passed to gcov and those functions with zero calls written to a text
    file, grouped by source file.

    It's also pretty ugly.

    Reviews/suggestions are most welcome :)

    I'm finishing a related script that patches the source with 'printf's,
    so any false positives are easy to spot and it's clear when some action
    or test exercises a previously untested C function. It already works,
    but is much uglier then this one ;)

    Here's example output of a run against 3.0. The number after a function
    name is its length in lines (as gcov counts them :).

    False positives include:
    ./Objects/weakrefobject.c gc_clear
    ./Modules/readline.c on_completion_display_matches_hook
