Tbh i never even thought about how long it takes to actually 
build the compilers. When people talked about compile speed, i 
thought they just meant how long DMD takes to compile something, 
not how long it takes to compile DMD. I can agree 100% that would 
be a hugely important issue, actually if something took 2 hours 
to build i wouldn't even bother.
