Some questions about this result:
1. Is it generally expected that snapshot tags should build on OSX? I thought it would be more likely to build than HEAD. Am I wrong? Is it preferred to build HEAD for general use?
2. Has this issue been fixed? I cannot find a reference to "WARNING: Title underline too short" (which might be the failing error? although the output continues for quite some time) on this list or on bugs.swift.org <Issues · apple/swift · GitHub, but presumably somebody has tried to build Swift at some point in the past few days
3. Is there something wrong with my config?
Sorry for asking a "hurr durr how to build" question, but I am still getting oriented with the build system and initial searching did not turn up anything relevant to the Swift project specifically.
