Re: [patch,c++] Generate correct (i.e., const) debug entries for arrays declared const but not marked READONLY

[Jason Merrill]

There's no need to track this on the decl, as the decl's type still 
reflects the constness of the declaration.  The issue is that the const 
applies to the array element type rather than the array type itself, so 
the code in dwarf2out.c needs to be fixed to find it there.
