+Subject: [PATCH] Let Bison generate the header directly, to fix build with
+ Bison 3.7
+
+Starting with Bison 3.7, the generated C++ file #include's the header
+by default, instead of duplicating it. So we should not delete it.
+
+Remove the code to add #ifdef guards to the header, since Bison adds
+them itself since version 2.6.3.
