I'm afraid you're indeed right there for a bit, but there's no point
in making it worse :-) It's not really as bad as you make it sound
like it is, imho.

I don't think it's that hard - I'll commit some of my current work in
progress to show what I mean.

There's no point in building *everything* shared. For example, LIBNDR
makes sense as a shared library, but there's no point in also building
NDR_RAW and NDR_COMPRESSION as shared libs. They should be included in
libndr.so.
