It's more that even though both are called "array of const", they are  
completely different things. They also don't support the same types.

You could say it is an unimplemented feature, but implementing it  
would require a lot of assembler code that's different for every  
architecture (and in some cases also for different OSes, since not all  
OSes use the same ABI and the ABI defines how C varargs must be  
passed). It is not a bug since the error message is given on purpose.
