I've just been bitten by the ghost of DOS when trying to unpack the source kit for GHC on a Windows (XP) system. It appears that the filename AUX is reserved (still crazy after all these years?). Unfortunately, the GHC source kit contains a file aux.dtd in .\ghc-6.2\src\libraries\HaXml\bugs So, when trying to copy this to my working system, I get strange errors that this file cannot be created. It's not a big deal for me -- I just unpacked the tar file on my Linux server machine, renamed the offending file, and the copy then works fine. But for Windows users without a Linux box to fall back on, this might be problematic. Maybe it's worth using another filename? #g ------------ Graham Klyne For email: http://www.ninebynine.org/#Contact
