--- Comment #1 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- The log file of the libitm testsuite is totally cluttered because it is not using -fno-diagnostics-color=never. This happens only for: libitm.c++/throwdown.C libitm.c++/dropref.C Other tests are unaffected, no warning when building libitm. Complete list of warnings follows: ../../../../gcc-trunk/libitm/testsuite/../libitm.h:150:13: warning: declaration of 'void _ITM_abortTransaction(_ITM_abortReason)' conflicts with built-in declaration
