Many times we need to debug some compile problem, and the > output is mandatory. As long as it's *possible* to expose the commands, I see nothing wrong with hiding them by default. I personally almost always use "make -s" these days, and would not mind if that became the default behavior. But there had better be a switch to do the other thing. The other make switch I use all the time is -jN (with varying values of N depending on what machine I'm on). If cmake can't provide an equivalent feature, that would be a large minus, because if you have a decent number of cores -j makes a huge difference in build time. regards, tom lane
