Is there an MD5 Fixed Point where md5(x) == x?

What is the bit size of long on 64-bit Windows?
Not to long ago, someone told me that long are not 64 bits on 64 bit machines and I should always use int . This did not make sense to me. I have seen docs (such as the one on Apple's official site) say that long are indeed 64 bits when compiling for a 64-bit CPU. I looked up what it was on 64-...
