Nice patch. Will apply it.

As for sending the patches upstream, I have already a whole set
including the one that allow building on Linux and the brings 64-bits
compatibility... (yes code written in 2007 still does not compile on
platform where sizeof(void*) != 4. I will add that one to the list.

So far I still have to hear from them. I have asked both to the PM and
the public forums who to send patches to, still have to get an answer....
