Specifically:
- use libtool so that the top level library contains the actual
objects, and not just the sub-archives, which the linker will just
ignore.
- create the source files via symlinks rather than referencing them
with relative paths. Doing it that way causes a 'make clean' to
delete objects in DtMmdb/ which is wrong.
- fix up utility/ - it seemed to be building more source files than
the original Imakefile listed. Other changes may need to be done
here if similar mistakes were made in other subdirs.
This patch fixes many warnings from the beginning of the build up to
and including the depend stage. Nearly all warnings should be gone
even with -Wall.
