As far as libtiff using Windows file APIs goes, it can be "cured" by using TIFFClientOpen() to specify use of the desired file access APIs. This requires writing some tiny I/O wrapper functions.

Thanks for all your help with this guys. In the meantime I've discovered something else that could potentially be helpful:-

FILE*  f            = _wfopen (path, mode);    // This is how libgdk_pixbuf opens the file at present

int handle        = _fileno (f);                        // and this is how it gets the (POSIX style) file handle

HANDLE hFile = (HANDLE) _get_osfhandle (handle);
// Potentially, the above could be used somewhere to
// convert to a WinOS handle, as required by tif_win32.c

It's a bit too early in the morning here for me to think too hard about this but at least I have several potential solutions to follow up!
