Investigating this one case, it appears that this is a gstreamer problem.

The line in artssink.cpp uses the gstreamer macro GST_ELEMENT_ERROR, which in 
turn uses the GST_FUNCTION macro, which is defined like this in 
gst/gstinfo.h:

#if defined (__GNUC__)
#  define GST_FUNCTION     ((const char*) (__FUNCTION__))
#elif defined (G_HAVE_ISO_VARARGS)
#  define GST_FUNCTION     ((const char*) (__func__))
#else
#  define GST_FUNCTION     ((const char*) ("???"))
#endif

Which references the glibconfig.h macro:

#ifndef __cplusplus
# define G_HAVE_ISO_VARARGS 1
#endif

Conclusion: the gstreamer test is bogus in gstinfo.h. The fix should be 
applied to gstreamer sources then.

Jens, can you report the issue to the gstreamer developers?
