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.

This issue is reported here: http://gcc.gnu.org/gcc-4.6/porting_to.html?
