This generetas a lot of errors, I have not a deep knowledge of Spirit.Lex source code, but probably it is necessary to change the code not only in the lexer class, but also in other points. Sorry, but I am not able to patch the code. I attach a very simple example which shows this issue." Feature Requests new To Be Determined spirit Boost 1.55.0 Problem
