+Subject: [PATCH] PIDL: fix parsing linemarkers in preprocessor output
+
+When PIDL calls out to C preprocessor to expand IDL files
+and parse the output, it filters out linemarkers and line control
+information as described in http://gcc.gnu.org/onlinedocs/cpp/Preprocessor-Output.html
+and http://gcc.gnu.org/onlinedocs/cpp/Line-Control.html#Line-Control
+
+With gcc 4.8 stdc-predef.h is included automatically and linemarker for the
+file has extended flags that PIDL couldn't parse ('system header that needs to
+be extern "C" protected for C++')
+
+Thanks to Jakub Jelinek <jakub@redhat.com> for explanation of the linemarker format.
+
+Fixes https://bugzilla.redhat.com/show_bug.cgi?id=906517
