You want neither (a) single threaded nor (b) the static run time =
library.

Single threaded implies that the library won't be thread safe.  [I don't
understand the point of having this as the default.  Responsible vendors
provide libraries that are thread safe but minimum the overhead when you
aren't multi-threaded.]

If you use the static run time library then you cannot allocate storage
on the heap (using malloc or new) from one DLL and then deallocate
the same storage from a different DLL.  This isn't practical with CORBA
so your best bet is to avoid the static run time library.  [Again, IMHO,
it is very unfortunate that the static run time library is the default.]

HTH,

Bruce
