[vox-tech] flex/bison and licenses

[Mark K. Kim]

They have a special exception to GPL for Bison:

   http://www.gnu.org/manual/bison-1.25/html_mono/bison.html#SEC2

As for Flex, if it's a BSD license, I don't see why you couldn't
redistribute the resulting file in propriatary software (as long as you
give it credit, I suppose, to follow BSD-ism, though I think the newer BSD
license removed that requirement.)
