If Musl, GNU Libc, and Android are all different operating systems, why are MSVCRT, MinGW, and Cygwin not different operating systems? Listing off examples is *not* providing an objective definition. The simplest reading of history that doesn't require any contortions is that MinGW and Cygwin predated configs with more than 3 components, but Android did not. Had those Windows-based platforms been introduced later, something like the configs that Saleem added to LLVM would have been used from the get go --- grouping the Windows-based platforms and grouping the Linux-based platforms are both advantageous ways of categorizing things, and advantageous for the same reasons. > How is that worse than forcing every program wishing to support MS-Windows to > introduce express support for 2 or 3 disparate and incorrect triplets?

You can take the latest version and do nothing else. Anyone that uses *-windows-gnu will have their build fail, just as it fails today. There is no problem. John
