Hello !
         I'm sorry if I'm not right, but it seems that few source files are
missed in 3.47version "csound_src.zip" (got from /newest dir on Bath ftp
site). First is "ugensa.c" (found in "csound.tar.gz" from the the same
dir). The others are files where some functions must be implemented:
functions, declared in "physutil.h" ("make_ADSR" and others), and
functions, declared and used in "MidiSend.c" ("midiOutOpen" and others). 
                     Thank you very much.
                        Best regards,
Yuri Pavlovetsky.

As has been pointed out there are files missing from csound_src.zip
I will investigate and complete the file.  Unfortunately I still have
hardware problems, so I am not sure when I can manage it.
