First, I can report that bootstrapping gcc-4.8.0 works if I use gnugrep instead of bsdgrep. The above explains why I had previously seen the failure as I was using an older bsdgrep. Second, an apology is owed to the clang gang as I attributed the problem to clang as it showed up on my system after converted everything over to clang. > I think it would be best to back out r246917 for now, until the > regression can be fixed properly.

I tend to agree with your assessment that r246817 should be reverted, because I hit this issue in configure scripts and there is a large amount of software that uses autotool for configuration. -- Steve _______________________________________________ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
