Since python 3.6, RegexFlags are instances of RegexFlag, not int. Passing re.UNICODE directly to the lexer will result in the generated lextab.py returning a SyntaxError. RegexFlag instances need to be explicitely converted to int. This solution does not break compatibility with previous previous versions of python that already return int values. fix #35 ref: https://docs.python.org/3/library/re.html#module-contents
