Gary,

YAZ is auto-compiled on the gcc versions 2.95.4, 3.3.4, 3.3.5, 4.1.2, 
4,3.0, 4.3.1 on Linux/FreeBSD/OpenBSD without errors.

Maybe gcc is broken on your platform (unlikely). Or, you're just using 
gcc in its C++ mode (likely). Check your makefiles. You might also - to 
test - compile vanilla YAZ on your platform and see if you get the same 
errors.

These type casts should not be necessary for C. Only for C++.
