Way back five years ago, we all compared notes on how long it took to build Wine on our systems. http://www.winehq.org/site/?issue=149#Compile%20Time%20Comparisons%20/%20Tip...
Today I measured it on a new computer (with a spiffy new Intel dual core e7200 processor with 2GB of RAM, http://kegel.com/new-computer-2008.html ).
Result: ... it takes me a bit longer today on this machine (11 minutes) to build as it did then on a dual cpu hot rod (8 minutes). I guess Moore's Law isn't quite keeping up with Wine's code growth :-)
