--- Comment #4 from Iain Sandoe <iains at gcc dot gnu.org> 2011-02-16 16:14:02 UTC ---
thanks, IIRC, when the patch was originally applied it was not possible to test
on Darwin 8 (libquadmath was broken for other reasons).

---

This is not an objection to the proposed solution - but - for the record:

I remain concerned that the libgomp test-suite is driven by xgcc (which does
not apply the fortran spec) and, thus, is different from the notional idea of
equivalence with the installed gfortran.

[if the fortran spec is used, I think you will find that the fails are also
resolved]

e.g.
