I have seen this myself when building, remotely, on Mac OS X. I don't know if this is something that should be fixed or
not.
I have not tried the pre-release 5.7.1, but this warning is also reproducible on Linux with previous versions as
described in [0]. I noticed no ill effects resulting from this, but perhaps the final output is not as tuned as it could be.
