I understand your point with the utilities. However this is a problem with
Csound itself. Some consoles won't print stderr. Some people prefer to pipe
all Csound messages to a file; I don't know how to pipe both stdout and
stderr to the same file. We could #ifdef this so the stub library prints
output to stdout and messages to stderr, and the csound library prints both
messages and output to stdout.

I don't think that this will work correctly with some of the utilities
(scsort, cscore, perhaps others) which send their output to stdout (the
sorted score) and any messages to stderr.

OK.  I guess my question then is which messages are going to which place and
what is the rational for the separation?  What possible advantages (if any)
would we be losing by doing this?

hmmm ... this seems to work OK for me ... or at least I don't remember a
problem.

Isn't printf redefined as err_printf anyways?  And does this become a moot
point in Cs5 when using the Message callbacks in the API?

Sorry, I am not too familiar with all of the specifics.

I could probably live with this change.  Cannot anticipate any problems at
this moment.
