Thanks; that's exactly what I wanted to know. The answer, then, is that FreeBSD is not fully compliant with ISO C99, although there is work in progress to add compliance. I personally don't understand why the avoidance of the built-in. It's worthwhile adding the function, but rather than doing this one at a time, and finding out 10 years later that FreeBSD is finally compliant (in 2011, after the 2009 version of the standard is out ;^)), it's probably a better idea to write an "external reference compliance program", so that you can compile it up, and find out all the undefined references at once, so that we can make a concerted effort. I expect this will have to be done by someone with access to the ISO C99 standard, unles it's postied online for free somewhere? -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
