This is a bug in the Qt header. Is Qt3 still maintained?

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

My question is - is Qt3 still maintained somehow, so the includes can be added where they belong, or do we need to workaround in in the applications?
