I think Tom is correct. IMO the questionable thing done here is asking
c_type_print_base to print details of the type when we have a pointer
member/method whose containing class/struct is anonymous (TYPE_NAME (type) ==
NULL). That just doesn't seem right.

I believe the proper fix is simply for c_type_print_varspec_prefix to honor the
SHOW parameter when it is calling other c_type_print_* functions.

In this function, the only cases which do not pass SHOW to the other type
printing functions are MEMBERPTR and METHODPTR, exactly where we are seeing
problems.

I'm working on a test case for this now, and will submit a patch when it is
finished. [It requires hand-written DWARF.]
