+Summary: gstreamer should use ISO __VAR_ARGS__
+
+Because Gstreamer uses the GCC specific style of handling variable
+arguments in macros, gstreamer can only be compiled by gcc.
+
+Gstreamer header files should use the ISO standard for variable arguments
+(since the ISO standard is supported by both gcc and ISO standard
+compilers).
+
+  #define debug(format, ...) fprintf (stderr, format, __VA_ARGS__)
+
+Rather than the GCC specific style:
+
+  #define debug(format, args...) fprintf (stderr, format, args)
+
+Note that the ISO standard does not support the "##" syntax to remove
+the extra comma if the variable arguments are omitted.  So, for example,
+the GST_PROPS_LIST() in gst/gstprops.h and some macros in gst/gstinfo.h
+will need some extra attention.
