They save the entire output, and compress that file to reduce the space used. They also generate a summary of warnings-seen at the end. This was very helpful when I was fixing all the compile-time warnings in 'lpr'. My first tactic was sending the output to /dev/null, but then I was stuck when "something weird" happened, and I had no idea where 'make' had been before it went off the rails. Especially when using 'make -j', it can be important to see the last 30-50 lines of make's output to understand what really went wrong. And sometimes what-went-wrong was that some file was being built with the wrong parameters, and I'd lose that info with 'make -s'. Also, I use these same 'wcmake' scripts on multiple platforms. These scripts don't care which version of 'make' needs to be used. -- Garance Alistair Drosehn = drosih@rpi.edu Senior Systems Programmer or gad@FreeBSD.org Rensselaer Polytechnic Institute; Troy, NY; USA
