> One deficiency I've come across, which seems to be well-known, is the M:N problem -- where one step takes M input files and has N output files. Make rules seem to expect to have only 1 output, and the workarounds like .SECONDARY prevent some features of Make from working correctly. Jeez, you know, this is the sort of thing that I would hate to get somewhat deep into using make, only to then discover. I often see hackers lamenting that a plethora of build tools exist instead of everyone just using make, but I'm not so sure that this state of affairs is less preferable. Maybe it's better if the build tool understands some things about the platform it's building for.
