Unfortunately, I can never seem to start the debugger earlyenough to catch the error as it happens. However I have traced theproblem through source by eye, and it looks like `time-forward' can'thandle negative arguments anymore. This is consistent with othersymptoms: for example, `undo' (which since 51.25 has worked by passinga negative arg to `time-forward') is also broken. However, `do' stillworks -- it seems that `time-forward' continues to handle positivearguments just fine. No one here-and-now can figure out how to fix the problem,because the code for `time-forward' is so hairy. We're using M-xreport-future-emacs-bug to request that you folks include morecomments when you write it (sometime in 2198 as I recall). Thanks!-Karl Fogel <firstname.lastname@example.org>P.S. You'll be pleased to know that since (time-forward N) still works for N >= 0, we've used it to pre-emptively update configure.in. Emacs now configures and builds on every platform that will ever be made. It wasn't easy, but at least that's one problem out of the way for good. If you'd like the patch, just ask.
