[Scons-users] Command builder multiple targets and multiple sources for a single command

[Daan De Meyer]

I've managed to find the issue. It turned out I accidentally added a single
directory in the list of output header files. This caused scons to produce
more than 9000 internal errors, each saying "error no dependency cycle
found ..." However, I believe this has already been fixed in a more recent
version of scons so I don't think there's anything actionable to be done
here.
