Eg: sprintf from newlib accepts a few c99 formatters, while coredll doesn't, which means you would get a discrepancy between the sprintf/swprintf.

Usually they are solved over and over again using the same methods. Perhaps we should document them, in a "how to port" kind of guide. - The missing errno. - The missing notion of cwd. - Missing getopt. - Missing child/parent IPC (pipes). - Others I don't remember off hand. Several problems are solved by importing code into the project. Eg: The missing getopt, is easilly solved by using a getopt from any BSD variant. I'm currently testing freegetopt to build a heavily reduced WinCE version of busybox. Hopefully with busybox we'll have rm, mv, mkdir, etc. With some work, busybox's ash may work too.
