Here is what /usr/doc/flex/copyright from Debian says:

  Flex carries the copyright used for BSD software, slightly modified
  because it originated at the Lawrence Berkeley (not Livermore!) Laboratory,
  which operates under a contract with the Department of Energy:

[legal stuff deleted]

  This basically says "do whatever you please with this software except
  remove this notice or take advantage of the University's (or the flex
  authors') name".

  Note that the "flex.skl" scanner skeleton carries no copyright notice.
  You are free to do whatever you please with scanners generated using flex;
  for them, you are not even bound by the above copyright.

You may be thinking of Bison. Bison is GPL, however they changed the
license a few years back so that the Bison output was not GPL.
