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. for libstdc++-v3/ChangeLog * testsuite/20_util/shared_ptr/atomic/3.cc: Do not require POSIX threads and add -pthread only on
