Nice!  Looking at liblex, it looks like we need to test headermaps  
(horrible apple feature), backtracking (new and shiny!), 6 of the 9  
trigraphs, escaped newlines and trigraphs in identifiers, unterminated  
block comments, nul characters in the middle of file, the MS charize  
extension, some random expressions in the pp expr parsing, and some  
even more strange stuff...
