Will TIFF be supported for Qt/Mac OS X 4.3?

Yes, but it requires libtiff to be installed on the system as we don't supply
it with the package.

Don't you use the following TIFF library?
/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources/libTIFF.dylib

If that is in the include paths then yes. Basically the test in:
config.tests/unix/libtiff
will be run, and if it succeeds we will use tiff.

Why don't you detect libTIFF by config.tests/unix/libtiff and use it?

Hello, Sugita-san. The config.tests test should detect libtiff if it's
installed. Maybe the script doesn't find the include headers? Where does
your platform install its <tiffio.h> file?

We can't use the libTIFF in the ImageIO framework as that is a private
resource of ImageIO and there is no guarantee that it will be there in
the future.
We are currently looking at including libtiff in 3rdparty so that you
can get the benefit regardless of what platform you are on (just like
libpng, jpeg, and mng). The license is currently under review in legal
and we hope to get this done before Qt 4.3 is released.
In the meantime, you can consider install libtiff using Fink or MacPorts.
