Does the generated code contain significant fractions of protected
elements of the library itself?  If not the generated code is a
mechanical transformation of the input and so only the license on the
input applies.  Even if elements of the library are in the generated
code you can apply a different license to them than to the library.  The
Gcc license does exactly that.
