I was thinking the same.  GCC has them, MSVC has them, STLPort has them,
probably others have them.

I guess it depends on whether you think it's more astonishing to have
any chance of high performance absolutely slaughtered even in MSVC
release builds, and to have different defaults for the checked-iterator
setting on different platforms, or more astonishing for the default to
be different from what the toolset gives you out-of-the-box.
