--- Comment #3 from Louis Dionne <ldionne at apple.com> ---
I just committed a fix:
commit 99f3b231cb21abc567c93813650cd76cfa614325
Author: Louis Dionne <ldionne at apple.com>

[libc++] Workaround timespec_get not always being available in Apple SDKs
timespec_get is not available in Apple SDKs when (__DARWIN_C_LEVEL >=
__DARWIN_C_FULL)
isn't true, which leads to libc++ trying to import ::timespec_get into
namespace std when it's not available. This issue has been reported to
Apple's libc, but we need a workaround in the meantime.

Can you please let me know if it fixes your issue? It does fix the reproducer I
created locally (and checked into the test suite).
