[Bug c++/25137] New: Warning "missing braces around initializer" causing problems with tr1::array

[chris at bubblescope dot net]

The following code:

struct S
{ int x[3]; };

void f()
{ S s = {1,2,3};}

With -Wmissing-braces (which is implied by -Wall, among others) gives:

warning: missing braces around initializer for 'int [3]'

In the specific case where a struct contains only a single array, adding the
extra braces doesn't really seem that useful.

The reason it would be nice to fix this that in the definition of tr1::array in
the TR1 specification (page 88, 6.2.2) says

2.An array is an aggregate ([dcl.init.aggr]) that can be initialized with the
syntax 
array a = { initializer-list }; 
where initializer-list is a comma separated list of up to N elements whose
types are convertible to T.
