There are several calls to setup_kfail passing gdb/x and gdb/y.
x and y need to be fixed.

According to gdb/testsuite/README I think (!) setup_xfail should
be used here instead of setup_kfail, since the problem originates
with gcc.

kfail = known gdb problem
xfail = known environment problem (e.g. compiler)

Ok with those changes.
[Though I can well imagine I'm missing something.
This part of the testsuite and c++ is a bit beyond me.]
