Sorry it took us so long to get back on this.  I've just refreshed the
patch at <https://gcc.gnu.org/legacy-ml/gcc-patches/2019-12/msg00690.html>:

- resolving some trivial conflicts within 30_threads/shared_mutex,

- updating some renamed test file names within 30_threads/this_thread, and

- dropping the obviated change to 30_threads/this_thread/yield.cc

and gave it a spin on gcc111 in the cfarm.

There weren't any changes to the libstdc++ results, according to
test_summary, not even in the unsupported (or any other) test counts.

> OK for trunk, thanks.

Given the approval and the lack of significant changes, I'll put this in
unless there are objections in the next 48 hours.  Thanks for the review!



Fix libstdc++ testsuite to handle VxWorks gthreads implementation

From: Corentin Gay <g...@adacore.com>

When implementing the support for gthreads in VxWorks, we stumbled on
a problem in the testsuite. In the libstdc++ testsuite, we
indiscriminately add the `-pthread` switch to the tests that require
linking against the pthread library. In certain cases, such as
VxWorks, the gthread interface relies on the system native threads
lilbrary and the `-pthread` switch does not exist.

This patch adds a condition for the use of the `-pthread` switch. It
adds it only if the target supports it. The patch also adds
`dg-require-gthreads` in tests that were lacking it.

libstc++/ChangeLog:
        * testsuite/20_util/shared_ptr/atomic/3.cc: Do not require POSIX
        threads and add -pthread only on targets supporting them.
