On Windows, for historical reasons, file names such as aux.c, nul.txt are not allowed. For aux.c, attempts to write such a file will result in an obscure error, for nul.txt the call will succeed but no such file will appear, ever, instead the effect will be equivalent to writing to /dev/null on Linux/Unix. Let's help users by refusing to create such files altogether, with an informative error message.
