+Subject: [PATCH] Don't link against libfl
+
+We can remove all references to yywrap by adding "%option noyywrap" statements
+to each flex source file that doesn't override yywrap. After this, we no longer
+need to link against libfl and so no longer get errors about undefined
+references to yylex.
