4821,Passing -optP-traditional to the preprocessor breaks the build.,gwright,,"The build of 7.0.1 breaks when the preprocessor is explicitly specified by the -pgmP option and the -traditional flag is passed using -optP-traditional.  The trouble is that most of ghc requires -traditional flag, but .cmm files don't.  The -optP-traditional option needs to be filtered out from the options passed when compiling .cmm files.",bug,closed,normal,,Build System,7.0.1,invalid,,,Unknown/Multiple,Unknown/Multiple,Building GHC failed,,,,,
