Hi, Folks
    I'm not sure whether this is a g++ or gdb bug, so I'm sending this report
to both bug mailing lists.  gdb 4.6 (and 4.5) can't find the type of a g++
anonymous (i.e. untagged) struct.  Here's an example:



struct
{
    int a, b;
} anon;


struct named_t
{
    int a, b;
} named;


main()
{
    ++anon.a;
    ++named.a;
}
