Since Csound doesn’t have macro concatenation predefined like in C (##), I had to defined as

```csound
#define C(X'Y) #$X$Y#

```

But since I use that `$C` a lot in the subsequent to emulate structures in Csound 6 (by prefixing fields with some ‘object’ name), I’m getting spammed with “defining argument” message on startup. How can one cut down _just_ those “defining argument” messages from being printed?
