This is a known problem in the lexer rules; I get the same.  However,
on my GNU/Linux box, using exactly the same version, this causes a
warning only.  You should investigate why this is a fatal error for


PS: It is possible to easily fix this problem in lexer.ll, however,
    the fix is very ugly since you must explicitly mention all states
    except `longcomment' (and there isn't an alternative to it).
    IMHO, it's better to stay with this harmless warning.
