+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.
+
+[Original patch taken from
+https://gitweb.gentoo.org/repo/gentoo.git/plain/dev-qt/qtwebkit/files/qtwebkit-5.212.0_pre20200309-bison-3.7.patch?id=69e618c88a9134f754264efc11aa0b1fdc028b88
