[Bug c++/16859] New: Empty initializer for array of unknown size spuriously accepted

[bangerth at dealii dot org]

Section 8.3.1/4 states that arrays of unknown size may only be initialized 
by initializer lists of size greater than zero. However, all gcc versions 
I have (and a good number of other compilers, btw) accept this code: 
---------------- 
int a[] = {}; 
---------------- 
That sounds spurious to me.

Confirmed.
What is really funny is that the C front-end rejects it with -pedantic-errors.
