I understand that that would be faster when the dependencies have 
changed but if they haven't then you just have to run the compiler once. 
Don't know what would be best to do though.

BTW, to just get the dependencies, would that be with the -deps and -c 
flags? Is the a better way? I mean if you just specify the -deps flag it 
will do a full compilation. Seems to me that skipping linking (-c flag) 
is a little too much as well for what's actually necessary. Would be 
good to have a flag that does only what's absolutely necessary for 
tracking dependencies.
