That's strange. I should've been more explicit about what I claimed to fix. gcc fails miserably if one tries to get a difference of two addresses whose target types are different and there's no implicit conversions available, so: const char **ccpp; char **cpp; int idx; idx = cpp - ccpp; /* NG */ idx = *cpp - *ccpp; /* OK, *cpp converted to (const char *) */ idx = *ccpp - *cpp; /* NG, (const char *) to (char *) */ but what I don't understand is that this produces only a warning: idx = cpp < ccpp;
