Once you're done with merging compile everything

Dynamics AX 2009 compare tool has some quirks. These quirks may sometimes conceal the new nodes.

So to catch situations like this - compile the whole AOT and resolve the errors.

It is very helpful to have compare the compilation output to a pre-roll-up environment so that you can identify the new problems caused by the roll-up/merge.

As always, comment your decisions and use //todo: to annotate next steps.
