Ouch, good point. I guess one has to consider _SECURE_SCL=0 as a
global setting. Perhaps the boost build system might want to make this
the default, given the past performance issues of MS checked
iterators, etc. even in release builds. (I haven't measured the
performance imapct for vc9 yet, but I did notice that it is not a
debug-only switch).
