Comment (by Simon Peyton Jones <simonpj@…>):

 In [changeset:"6c1aba4ff27371fddfc0dce5f9256c97edf16eea/ghc"]:
 {{{

 revision="6c1aba4ff27371fddfc0dce5f9256c97edf16eea"
 Warn if you use ANN annotations with a stage-1 compiler (Trac #4268)

 This makes us give a civilised warning when we hit an
   {-# ANN f foo #-}
 pragma in a stage-1 compiler.

 We decided that, since it's a pragma, it does not need a language
 extension flag to enable it.
