Hum. Does it hurt us to simply update to 600 everywhere? If we can, I'd prefer that as a solution. But if that causes more problems than it solves, I'm ok with this as a solution. I would like the comments updated to mention the reason for XPG6; just saying that Solaris requires it for C99 and later seems sufficient. r~
