Ahh interesting, I did stumble upon your mail before but I missed the bit about the "outfile" option, so I got stuck with that. I guess this option is flex-specific but at this point I just want it to work, portability is less important since only I need to generate the yacc/lex output. I was also a bit confused on how to deal with the header produced by yacc but the documentation ( at http://www.gnu.org/software/automake/manual/html_node/Yacc-and-Lex.html ) explains how that is dealt with. Thanks for clueing me in!
