I don't understand what you mean. The experiment I did yesterday *did* eliminate both ReadFiles. However, I don't think Make can eliminate both ReadFiles *by default* because Make can't assume that the user doesn't use any symlinks unless the user tells it to assume that. > I have found the following set of GCC flags to have great impact > with the speed with wish Cygwin flies. How gcc should be called when compiling Cygwin is an interesting question, but it's not the one I'm asking here. I hope the people from RedHat who compile the Cygwin packages that go up on the Web sites consider your suggestion, though :-). jik -- Want to unsubscribe from this list?
