When build with -DDEBUG, tc build fails with: q_gred.c: In function ‘init_gred’: q_gred.c:53:17: error: passing argument 2 of ‘fprintf’ from incompatible pointer type [-Wincompatible-pointer-types] 53 | DPRINTF(stderr, "init_gred: invoked with %s\n", *argv); | ^~~~~~~ | | | FILE * This is due to the DPRINTF macro call. Indeed DPRINTF is defined as a two-args macro when -DDEBUG is used, while it uses 3 args in this call. Fix it simply dropping the useless first arg.
