* Adjust the options to make them either accept multiple occurrences or be
optional so that compatibility with GCC is accomplished. * Implement the -print-file-name option in an attempt to provide the same functionality as GCC. Unfortunately, without loading the cpp or c config files, this option won't help much. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18189 91177308-0d34-0410-b5e6-96231b3b80d8
