-****************************** SPECIAL WARNING: ******************************
-
-	Due to a bug in some versions of clang that's very hard to workaround in
-	the upgrade process, to upgrade to -current you must first upgrade
-	either stable/9 after r286035 or stable/10 after r286033 (including
-	10.3-RELEASE) or current after r286007 (including stable/11 and
-	11.0-RELEASE). These revisions post-date the 10.2 and 9.3 releases, so
-	you'll need to take the unusual step of upgrading to the tip of the
-	stable branch before moving to 11 or -current via a source upgrade.
-	stable/11 and 11.0-RELEASE have working newer compiler. This differs
-	from the historical situation where one could upgrade from anywhere on
-	the last couple of stable branches, so be careful.
-
-	If you're running a hybrid system on 9.x or 10.x with an updated clang
-	compiler or are using an supported external toolchain, the build system
-	will allow the upgrade. Otherwise it will print a reminder.
