Why so? Normal users don't need to run make depend (explicitly). And 
those that would be toying with the dependancies would need to know what 
they're doing anyway. Indeed, you could even have two targets, 'depend' 
which builds the dependancy file if it doesn't exist and 'regen-dep' 
which forces dependancy regeneration.

It's non-standard behavior, though. And, unless I missed something in 
the docs about building from CVS, there's nothing saying it needs to be 
done manually, and the eventual errors you get from not calling it 
aren't indicative of what the real problem is (who would think missing 
header files are caused by forgetting to generate dependancy info?).
