Original commit message from CVS: * gst/goom/Makefile.am: Don't compile lex or yacc outputs with warnings, but add other CFLAGS * gst/goom/goomsl.c (gsl_instr_set_namespace), (gsl_instr_add_param), (iflow_execute), (gsl_enternamespace), (calculate_labels), (gsl_read_file): * gst/goom/goomsl_lex.l: * gst/goom/goomsl_yacc.y: * gst/goom/plugin_info.c: Remove a few live printf, and fprintf, replace exit() calls with g_assert_not_reached() if it not optimal for a library
