I think the URL field explains it in detail. Under 1.8.1, with that example,
output from <exec> is never displayed, nor is any subsequent output from Ant.

It is possible, and I will try to investigate the root cause, but issues
involving stdio are especially nasty to track down so reverting the problematic
patch seems safest.

Right. And if I set it back to false on Linux, everything is fine. I will
double-check on XP, but I think platform-specific differences in stdio handling
meant that there was no problem on Windows to begin with.
