Hmm I see. Still, the above code is not easy to read IMO.
I'd suggest instead the following which is easier to read and understand:
__gnat_to_canonical_file_list_next (void)
{
static char empty[] = "";
return empty;
}
That's actually a change I was about to commit since we've done it recently
at AdaCore, so OK with the above variant.
