well the trick avoids using $(shell ... pwd) in Makefiles for each recursive invocation of "make". $(shell) is fairly expensive; by reducing the number of it to exactly one (instead of ~100 in 1.1.5.6) it was possible to reduce the time to "make" a (nearly) built tree significantly, on one PC by about 10 seconds from 15 to less than 5; and Clarence Dang has seen even greater differences. For a user who compiles her/himself this doesn't matter that much but for a developer who often makes a small change and then recompiles it saves a lot of waiting.
