+      The newlib "team" rolls new releases about once a year (december).
+      This is quite a long time between releases, in case code was fixed.
+      
+      Saying 'Y' here will allow you to use the bleeding-edge code from
+      the CVS repository. This may or may not fix your issues, may or may
+      not build, may or may not crash your machine, may or may not withdraw
+      money from your bank account, may or may not date your girlfriend,
+      may or may not resurect Elvis... :-)
+      
+      In a word: use the CVS snapshot at your own risk!
