Has the AJ default outlived its usefulness in general? > Well, I just reported a problem to NAG (www.nag.com) with their Fortran 95 compiler. The bug was found by phkmalloc and the AJ setting. NAG fixed the bug within 3 days and supplied a new binary. BTW, this is the only native Fortran 95 compiler for FreeBSD. I told NAG's tech support about the AJ feature and it appears NAG found at least one other bug with this set. I think AJ should be left set in the DP releases with a prominent note in the RELNOTES about the possible performance impact. -- Steve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
