I disagree. The struct definition, although only 7 lines in size, is
tricky and certainly copyrightable.

I don't want it to give it away in public domain; instead I've added
the GPL copyright notice to it now. Since the module description says
LGPL, it effectively means the file is under LGPL.

Why would this be a violation of Bison's license? Because the bison
output contains a significant portion of bison code (not just data
generated from the input files and the DFA)?
