Vorbis dev - Jun 2000 - Makefile dependencies in vorbis-tools

I've been trying to tackle the vorbis source.  I ran across what I think is
a
missing dependency in the vorbis-tools directory.  Since ogg123 and vorbize
are staticly linked to libvorbis and vorbisfile, when those file change, the
executables should be rebuilt.  Below I've attached a patch.  (I hope it
works.  I am sort of new to patch and diff.)

BTW, I've been trying to find a good introduction to DCT/MDCT.  I'm
familiar
with the concept of basis functions, I've just never run into discrete
cosine
transforms before.  Does anyone have some favorite signal processing texts?

There are some papers by James D Johnson in IEEE journals. I think the book
"Digital coding of waveforms" by Jayant and Noll should also help.
More on
Basis functions may be obtained from a good Linear Algebra book like the book
by Gilbert Strang. Hope this asnwers your question

That was almost exactly what I was _just_ about to commit! Except vorbize
depends on libvorbis, and ogg123 depends on vorbisfile.

Also removing ogg123 from the main build. Vorbize should be fine.
