I've just taken a look at this, and I think that if we're going to 
switch from static to dynamic then we might as well just do it. 
Otherwise we're not going to get the testing we require.

I also see that in r7701 you've dropped the use of libtool - I really 
recommend against this. I know it has its own interesting quirks to work 
around, but it does have the magic to make things work. Interestingly 
enough the comment mentions libtool was dropped, but not why?

If you can get libtool to work then this bit will be handled automatically.

Paul started some work on moving the private functions into a 
liblwgeom_internal.h file so that liblwgeom.h is just the public API 
file. It would be great to finish this section of work.

That will probably have to wait until testing :)
