Hi Taco,
on the Debian side we got a bug report that with the switch from
TL2007 mpost to TL2009 mpost the same file suddenly makes mpost
return 1 (failure in shell) instead of 0.

Version in testing is 2007.
It turned out that the the following line
tracingchoices := 1;
seems to made the difference. When I comment that mpost returns 0,
otherwise on. The following minimal mp file exhibits this point:
tracingchoices := 1;
beginfig(1)
path pathb ;
pathb = ((0, 0) .. (40, 25));
endfig;
end.
With tracingchoices == 1 mpost returns 1, otherwise 0.
Simple question: Is that intended or a bug? I checked the current
mpman but there is nothing mentioned about return values around
the tracing* pages.
Best wishes
Norbert
