Yes, lib.cpp is not compiled again.

OK, Core_pch.pch is listed, but only as "Order-only dependency":
http://martine.github.com/ninja/manual.html#ref_dependencies
Does it work when you make the pch a "Implicit dependency": change '||' to '|'?
This could be fixed in you pch macro by making each source file depend on the
pch file.
Or is this already done? Then you have found a bug in the ninja generator.
