 #define COMM1 / ## /
 COMM1

I did a little digging in the code with this one.  On Windows it definitely
does treat /##/ as an extension for Microsoft mode
(see TokenLexer.cpp:467).  Perhaps there is a way to test for both cases,
but I'm not sure how to set it up.  Is there a way to check for grep failing
or an empty file in this case?
