+Subject: [PATCH] Fix broken build due to C++ template behind C linkage
+
+glib/gatomic.h since 2.68 includes type_traits, which causes a compilation
+error:
+In file included from /usr/include/glib-2.0/glib/gatomic.h:31,
+                 from /usr/include/glib-2.0/glib/gthread.h:32,

+/usr/include/c++/10/type_traits:2308:3: error: template with C linkage
+2308 |   template<typename _CTp, typename _Rp>
+
+As libsigrokdecode.h declares extern C linkage itself where necessary,
+remove it from pulseviews include statements from the last two occasions.
