Changes committed to cws vs80compat

Some notes are due to changeset ea3a9145b615 in cws vs80compat:

 * the namespace lookup things are just annoying
 * as well as the non-working PSTR conversion
 * the conditional operator problem is though clearly a compiler bug,
   what seems to happen here is that the whole expression results in a temporary
   ITextLayout, that happens to have no vtable & thusly crashes subsequently
   as per 5.16 3 item 1, and since both types are reference-compatible, they
   should bind directly and not create any temporaries inbetween. the resulting
   expression type should be ITextLayout&, which again should bind directly to
   the method parameter.
   - anyways, this idiom generates a warning, so the compiler is still safe to
     use in WaE mode.
