huh, what doesn't work? I've just finished an x86_64-pc-linux-gnu
bootstrap with your patch included, added the above to the
async_io_?.f90 tests, linked them to gfortran.dg and ran the tests there
(both 32 and 64-bit multilibs), all PASSed and I verified that they were
linked with -lpthread.

Do you have a pointer to that previous discussion?

First of all, we need to see and understand the failure mode, if any.
Making this work with the testsuite is a secondary matter only, and I
can certainly help with that if necessary.
