Is Qt3 still maintained? This seems to be a common c++ issue since the begining of 2011. Some Qt3 headers use ptrdiff_t which is defined in stddef.h. They also use some c++ headers, and rely on them to include stddef.h. However, since GCC-4.6, those c++ headers do not include stddef.h anymore. So, include <stddef.h> fixes it.
