   case '\r':
+    if (CurPtr[0] != Char && (CurPtr[0] == '\n' || CurPtr[0] == '\r'))
+      Char = getAndAdvanceChar(CurPtr, Result);
     // If we are inside a preprocessor directive and we see the end of line,
Should we only do this in the `\r` case? If I understand correctly, we're basically saying, if this is a CR, and the next byte is an LF, advance one more and do the pre-processor stuff.
