There is no problem linking static libraries into shared libraries, I
do it every day.

MSVC issues with its runtime incompatibilities are fairly specific to
MSVC. And those issues are not related to static libraries per se
since the same problems can occur with shared libraries. Basically,
you should always link with the shared runtime, unless you dead sure
know what you're doing and really have to link with the static one.
I'm not even sure they still ship the static runtime.
