OK for me too. I suppose this is not too difficult to automate too.

Before going furhter let me tell you that I'm the guy running the
regression tests on IBM, SGI and HP. There was some discussion on why
thet were not update daily and some guessed that they were not
automated. First of all: they are automated and normally run daily by
means of a cron job.

So why have'nt they run for quite some time now: well I fail to compile
the regression test tools (exactly the reason why this thread started)
on all platforms all of a sudden (well not all of a sudden as I don't
verify the results every day). I'm currently in contact with IBM and HP
to help me out and find workarounds or compiler updates to compile these
tools succesfully. But this takes time.

If you have questions about the regression results (and since I don't
verify the results daily), you can always contact me (that's why I've
put my name on the IBM regression test page for instance) and I will try
to help you as good as I can.

To answer another question in this thread: no, running the regression
tests does not eat to much resources. They run every night as you also
can see on the IBM regression test page.

A big problem IMHO though is that few authors verify the regression
status on all the different platforms. How could one otherwise explain
that no one ever contacted me (even during this discussion) directly
regarding some questions he might have regarding the regression tests
(although my name is clearly visible on the status page for that sole
purpose). This suggests that not many have ever taken a look at the
status page for IBM/VisualAge. Actually only one developer ever
contacted me asking for help to port his library succesfully to
IBM/VisualAge. (don't get me wrong, I don't want to criticise boost
developers who are all doing a great job but I'm just trying to indicate
that it's not easy either to port the libraries).

And again, I don't have the time every day to verify the regression
tests and to read the ml (due to workload and/or traveling). So I
usually find out if something breaks a week or two after the
modification is made. And at that point, it's very difficult the exact
reason why the test breaks almost having to reverse all changes until
the situation where it worked and from then on trying to find a workaround.
