Ah ok, I didn't test it but I thought `--extra-cflags` was standard for 
Autotools, I guess it's not.

One thing you could try to troubleshoot is to put the following at the 
very top, before all other code, in any files where the `DBG()` macro 
isn't working:

```
#define DEBUG 1
#include <libxfce4util/libxfce4util.h>
#ifndef DBG
# error "uh oh!"
#endif
```
