Is this a bug in the WATCOM 9.0 preprocessor?

/* Input file test.c */


#define A	AA
#define g(x, y)	x ## y
#define gg(x)	g(x, A)

extern g(B, A)();
extern gg(B) ();

/* End of test.c */

Output of preprocessing phase:

extern  BA();
extern  BAA ();  <----- Isn't this wrong? Shouldn't it be BA ();
