* lex get a parse-error when chewing on a file produced by yacc.
*
* The errormsg is:
* lex.l:90: parse error before '1'
This is because the grammar file tries an yywrap() when it is already
defined as a macro or something. I just commented it out, the "real"
way to solve it is to #ifndef yywrap or something.
* If I'm not to mistaken, others have had this problem too.
*
* Is there someone out there with a longer memory than mine, who remember
* what the solution was?
I don't have a longer memory than yours, but I happened to save the
patch I needed to compile piewm on FreeBSD. It should be more or less
the same for tvtwm (but you obviously need to take out the parts about
xpm). If it works for you, please post how it goes.
