------- Comment #13 from dominiq at lps dot ens dot fr 2010-03-12 10:38 ------- I just got the failure today at revision 157401 on x86_64-apple-darwin10. I have saved the build directory and restarted for a successful bootstrap. Comparing the config.log files in x86_64-apple-darwin10/i386/libgomp/config.log and _fail/stage3-x86_64-apple-darwin10/i386/libgomp/config.log, I see
