Alternatively, it can also be fixed by - Moving TestHarness.h before _XOPEN_SOURCE - Undefining _XOPEN_SOURCE for MOZILLA_CLIENT

Comment on attachment 8692403 [details] [diff] [review] Raise POSIX level https://treeherder.mozilla.org/#/jobs?repo=try&revision=7712d76874d2

Comment on attachment 8692403 [details] [diff] [review] Raise POSIX level Thanks. This fix is good because TestHarness.h isn't available in builds outside of Gecko. Please don't land this patch directly -- I'll upstream the fix and include it in the update in bug 1225703.

Upstreamed: https://github.com/kinetiknz/cubeb/commit/84a6e75dcc4e692f2e4ba1a884b0e1f6daf4da46

Builds fine now and as long as bug 1219480 and bug 1225703 stay on the same release train. Thanks.
