"Me too". Can I please, rather than piling on to a target list,
replace the whole xfail-list with the equivalent of "target { !
large_long_double }" (an already-existing "effective target")?
I'll leave the thought of running the test only for
large_long_double targets (qualifying the dg-do run) instead of
an xfail-clause for maintainers.
