Because of buffering, you can't use such functions directly. So there  
seems to be essentially two methods, first, add a byte count in each

tweak the skeleton file for your purposes.

I think this list is as much Flex there is, but strictly speaking, it  
isn't distributed under a GNU copyright, but a BSD one.
