I've checked the file `compiler/prelude/primops.txt.pp` which is processed to generate the file I'm having problems with and that file is fine. I've cloned a new copy of the repo and done the usual `perl boot && ./configure && make` only to see exactly the same result. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9828 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

If I use `gcc-4.6` in the command above instead of just `gcc` the build proceeds past this point. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9828#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Comment (by Herbert Valerio Riedel
Please revert this commit, it is horribly wrong. I'll have a proper look later, but not supplying `-traditional` to the C preprocessor is the cause of #9828.
