I don't know whether any of these differences matter to R, but some things to look out for are:
- you can't unlink a file while it is open - filenames are not case sensitive - file permissions have strange defaults (everything is executable) - I think the executable format still needs to be Windows format - There's no such thing as a ptty - You'll probably need X11 for graphics, and will lose support for Windows metafile output (wmf) > > I was wondering whether this information is likely to be useful to > others, and if we should spend any time looking in to ways in which the > configure/build/install code could be modified to allow a standard > install. > What is the advantage of building this? I don't think we want to support platforms just for the sake of supporting more platforms, but if there's a real need for it, that would be different.
