I believe that the default should match the VC default, which is 1.

This has no performance implications. Whether _SECURE_SCL is 0 or 1 in a
particular project is decided by the user, not us. The autolink code will
check the macro value and attempt to link to the appropriate Boost library.
What is _built_ by default should match what is _used_ by default; it
doesn't matter which one is faster, the choice is not ours to make.

Not defined means "on" in debug builds, "off" in release builds. Defined to
0 means off. Defined to 1 means "on" in debug builds, "off", warning and
redefintion back to 0 in release builds.

If we build no debug libraries, this default doesn't matter for MSVC. If we
do, the default should again match the compiler default, either 1 or not
