As I said, I don't have gcc 2.95 installed so I didn't test it.
We use a similar definition in uDAPL, something along the lines of
#define foo(...) bar(__VA_ARGS__)
I bet the initial fmt parameter is confusing it.
In kDAPL, the debug print function is defined as static inline
function when debugging is on and an empty macro when it is
off. That might be easier than fighting with the C preprocessor.
