I am using automake (GNU automake) 1.11.1 from Debian squeeze.

The code didn't trigger the bug and I couldn't easily reproduce it by
modifying it. It involves considerable effort to modify my existing
project and upload it to the FreeBSD build machine and I don't have time
to do that, now. GNU make does not misbehave this way, so for now I'll
use that.

It happens reliably with any N in make -jN.

Yes, that works as expected and executes the right command (the one also
executed without -jN).

I am using FreeBSD 8.0-RELEASE-p4.
