Should that be static_cast not reinterpret_cast? A reinterpret_cast from void* is technically undefined in C++03, see http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1120 and http://homepage.ntlworld.com/jonathan.deboynepollard/FGA/reinterpret-cast-and-pointer-to-void.html Although GCC will do the right thing, if a static_cast will suffice then it should generally be preferred to reinterpret_cast.
