Missing debug information for decls in empty blocks

[Nicolas Setton]

Hello,

In the context of examining the state of debug information generation with GCC
3.4 and GCC 3.5, we found that nothing is generated for "foo" and "my_struct"
in a construct like:

 
         int main (void)
         {
                 {
                    typedef struct {int x;} my_struct;
                    my_struct foo;       
        
                 }
         }

Is this expected and/or intended ?  This is new compared to e.g. GCC 3.2.

I can see how this happens, and so would be happy to open a PR and post a more
detailed analysis as well as a tentative patch if this is considered a bug.

Many thanks in advance for your help,

Nico
