The _RWSTD_INSTANTIATE_TEMPLATES part is an implementation detail
of _RWSTD_LIB_SRC. If we were to add another detail like that we'd
have to also remember to update export.cpp. That seems just as
brittle as what we're doing now (i.e., not #defining _RWSTD_LIB_SRC).

I see. You're adding a #pragma comment to _config.h that expands
when _RWSTD_LIB_SRC is #defined and you need it to expand in all
library sources, correct?
