I've now regtested the patch on i386-pc-solaris2.11 and
sparc-sun-solaris2.11: no regressions and the new tests all PASS.

However, I still don't understand why you insist on the hack with
putting the async_io_*.f90 tests into the libgomp testsuite.  Why not
just make the pthread requirement explicit with

{ dg-require-effective-target pthread }
{ dg-additional-options "-pthread" }

and put them in gfortran.dg where they belong?
