now, the rest I don't know how much of it I can do without breaking the protocol's compatibility. client_state_t has moved back to client.h in qw_common and uquake. Seems like that's a step backward, but the way it was being used while common was far worse! This required massive reworking of headers and such. Speaking of using cl (the global client_state_t) badly, the sound code did exactly that. Mercury should be shot for not fixing that when he did the sound_lib.a stuff. The fix illustrates what we need to start doing to the code to make modularization possible. I'll be sending a message to the list about this shortly..
