Surrounding all the comments that weren't within a section of C-code like 
this:
%{
    /*******************
     ** Comments Here **
     *******************/
%}
worked and got lex to generate lex.yy.c OK. Although I'd imagine there 
might be a better way of doing it and as Glynn suggested do the comments 
really need to be there?

When we go to compile lex.yy.c however there are further errors:
