Thanks Luigi, yes that's exactly what I was referring to. I have previously done a full port of LuaTex (ver 0.76) to a native Windows build with Visual studio (no MinGW32 involved) but I just want to use MinGW32 for version 0.80 --- nothing urgent, I just like to check the builds for new releases. Just want to rule in or out whether the 0.80 build scripts are temporarily broken for Windows/MinGW32 at the moment. Warm wishes Graham
