Removing the xfail is okay. However, I wonder whether it would be better 
to leave a reference to the PR in case the failure pops up again. As the 
code is ill-defined, the failures might pop up in the future and the 
reference can help with analysis.

OK - as is or with an updated reference to the PR. – For the branch, it 
is the RMs' call when it can be committed.

Please wait with the committal until GCC's web mail archive works again 
for gcc-cvs.

Thanks!
