+= can be repeated per target, so it's not a syntax error. Do the  
values make you concerned about the semantics of this? Anyway, tell  
me why you think this is a typo.

You have vm sources and images recorded from Darcs, but not the most  
recently bootstrapped materials. Delete vm.c and vm.h (and your image  
files most likely) and re-run make to have the Makefile invoke wget  
to get the new VM sources, which define InterruptFlag. This was  
recently discussed on the mailing list. Then run "make bootstrap" to  
run the vm with the latest downloaded image to make slate.image.

We have not done any work to establish 64-bit portability. You are  
going to have to investigate this yourself, for the most part. Slate  
should build correctly on regular Ubuntu, however.
