        This is useful to speed up things, since all the functions in the funcs
        list will be put in one compilation unit.

        Arguments
        ---------
        funcs : seq
            list of functions to test
        include_dirs : seq
            list of header paths
        libraries : seq
            list of libraries to link the code snippet to
        library_dirs : seq
            list of library paths
        decl : dict
            for every (key, value), the declaration in the value will be
            used for function in key. If a function is not in the
            dictionary, no declaration will be used.
        call : dict
            for every item (f, value), if the value is True, a call will be
            done to the function f.
