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;
