That patch fixes three of the four warnings produced by gcc -Wcast-qual.
The final one is here:
void *
hash_insert (Hash_table *table, const void *entry)
{
...
return (void *) entry; <<<=======
}
What's the gain in fixing three of them if one still remains?
That last one looks unavoidable, given my requirement that the
second parameter retain the `const' attribute.
FYI, there are similar const-removing casts in many other modules.
Look at all of the functions like memchr, memmem, strdup, etc.,
that take a const string and return a non-const pointer into that
same string.
