The "expr" is being called with non-POSIX arguments by the w3c scripts. > Hmmmm.

The correct way to handle the "continuing brokenness" is to provide patches that will get applied to "libtool". Also, you complaint about different versionsion of FreeBSD being different is wrong: POSIX compliant scripts will call the command with POSIX compliant arguments, regardless of the FreeBSD version. Just because you can get away with it on older versions of FreeBSD doesn't mean that the patches shouldn't be applied there, too: they should, because it's important that the resulting scripts be standards compliant, even if the particular version of FreeBSD you are using has an implementation of "expr" that illegally extends the standard. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
