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
