[CM] Syntax error in fixed argument declaration

[Bill Schottstaedt]

That error should only occur in Guile 1.4 or earlier, and define* is
defined in fix-optargs.scm, so I don't understand what is happening.
The Help:About Snd menu item will tell you which Guile Snd thinks
it is running, and at the end of the info is a list of the files from 
Guile that Snd has loaded.  I'd start there -- perhaps you're actually
getting a much older version than you think.
