As it happens, Bison can also be used to develop non-free programs. This
is because we decided to explicitly permit the use of the Bison standard
parser program in Bison output files without restriction. We made the
decision because there were other tools comparable to Bison which
already permitted use for non-free programs.
flex appears to be under a BSD license.
