[Boost-build] What is the difference between link=static and runtime-link=static

Hi
I'm trying to determine if I need runtime-link=static when building the test suite?
What runtime-link do exactly?

It seems the link=static is selectively overridden, but not runtime-link=static?

I'm targeting VxWorks 7 which doesn't support shared libraries universally on all processors yet, so I've been focusing on static, so I can build shared libraries, they just might not work.

Happy new year,
