a little different than the one to generate the document. This caused
wrong page numbers.
Fixed sourcing of index.so. The hack of handling it separately is no
longer necessary. This hack didn't quite work - the page numbers and
columnization of the index were wrong.
Fixed warnings about not being able to source index.so.
Fixed generation of `index' in the source directory.
Don't bother removing `index' after creating index.so. `index' gets
created again when the final document is built and it's too much
trouble to remove later.
Fixed dependencies. The long {SRCS} list in 4.4lite isn't quite
right and got broken to allow centralized rules.
