I have purchased Borland C++ (through the attractive TC++ upgrade
offer).  It contains a DLLDEMO program that compiles and works.  The DLL
defines a paint call for a bitmap object.  The samples main program
takes this and plots the bitmap in succession to make it move (kind of
like animation only slower!).  

IMHO this shows that Borland C++ supports the development of DLLs.
Also IMHO I wouldn't say for sure that you could do animation (quickly) 
this way but I suspect that SDK would be no faster with the same approach.
