Woops. Meant to bump everything to 1.4.
Not sure what would be involved in updating them to use mingw. Though, there shouldn't be much change involved... If I was trying to cross build something I would use the standard --platform=ARM... or whatever the flag was, and have the autotools pick up the right compiler.
Though, if mingw crossbuild is different, it might be more useful to do it with cmake instead. tdev's cmake patch might be of some use. The only change I would want with the cmake though, would be to have it in its own directory (maybe trunk/ois/cmake) and let it generate project files there. Not sure what folder it is in now (only glanced at it so far).
