        * buildsym.h (pop_context): Convert to function, defined in
        buildsym.c.
        * buildsym.c: Include gdb_assert.h.
        (pop_context): Implement as C function.  Add check for stack
        underflow.
        * dbxread.c (process_one_symbol): Complain and stop processing
        that symbol if we are already at the top of the context stack for
        a function-end N_FUN (this would imply an umatched RBRAC).  Ditto
        when processing N_RBRAC.
