LexError on vertical tab \v

Parsing some C++ that uses '\v' I get the following error.

warning: -- rust-cpp parse error --
warning: There was an error parsing the crate for the rust-cpp build script:

warning: In order to provide a better error message, the build script will exit successfully, such that rustc can provide an error message.

Right, that's an expected limitation: The code within the macro still need to be valid rust tokens. I added a notice in the documentation about that in commit a9af87b0666d47846630dad262e87eb2fbdd3ba8

So you must change your code to use the ascii escape sequence (i believe that would be \x0b )
