Perhaps I have misunderstood Andy, but I thought he suppose to have a
class MD5 that already exists as e.g. extension. But it has no
e.g. rb_md5_new function serving as C constructor like all built-in
classes of Ruby have!

In another extension, he wants to create an instance of just this MD5
class on C level.

I have already send an answer for that case. If I was wrong, however,
please ignore my sermon :-)
