Because if g_strdupv() is prototyped as 
 
 g_strdupv (const gchar **str_array);

Then 

 char **a = g_strdupv (some_arr);
 b = g_strdupv (a);

Is not legal - there is no automatic conversion here. You have 
to write:

 b = g_strdupv ((const char **)a);

Of course, then you need casts for const arrays, but the way we do it,
people who don't use const never have to case, people who
use const, have to cast sometimes.
