FWIW, not that elaborate (no compiling and no X11 GUI), bit I still have MS-DOS software around (binaries) that work on my WinXP machines. I don't have to run them often, and I don't run them more often than I have to :) but the only ones of these oldies that I found don't run anymore are system tools. Which is ok... these are for system maintenance, and I don't need maintenance tools for 286 MS-DOS machines with FAT file systems. So far I also haven't had any problems reading older files with newer software from that "censored" manufacturer. (Which shouldn't be constructed to mean that I don't think that using open formats is a good thing.)
