While the thing is under development, it probably makes sense to have an `assert ()'. Hitting these assertions wouldn't be a problem if there was a separate GC development branch. In the meantime, `printf ()' seems better suited than `scm_c_issue_deprecation_warning ()'. > Let's just remove the variable, since scm_i_last_marked_cell_count is a > more exact name. OK. Thanks, Ludo'.
