OK, second take then. We keep everything the same but fix it differently in tif_win32.c. In TIFFFdOpen(), we use _get_osfhandle() to convert the given ifd into a HANDLE that we pass to TIFFClientOpen(). In the calls to TIFFFdOpen(), we call _open_osfhandle() to allocate an fd corresponding to the HANDLE.

If you can submit a tested patch, I will be happy to commit it.

Does anyone know where I can get a test file? :) Is it enough to generate sufficiently large image (say of constant color) with no compression?

Are the _get_osfhandle() and _open_osfhandle() functions available in older versions of Windows? (e.g. Windows '98?).

According to MSDN [1], it is. But then I have no idea how accurate MSDN is. :) MSDN also shows _get_osfhandle() as returning an int but on my MSVC 2005 io.h I see it returning an intptr_t.
