+Subject: [PATCH] Do not use bool as a field name
+
+C99 aliases `bool` to `_Bool`, and C23 introduces `bool` as a reserved
+keyword. Let's avoid using `bool` as a field name.
+
+Upstream-Status: Backport [Backport from glib to bunlded version in pkg-config https://github.com/GNOME/glib/commit/9e320e1c43a4770ed1532248fe5416eb0c618120]
