question on override

[bill lam <cbill.lam@xxxxxxxxx>]

I want to know will builtin dll always call other builtin dll or it depends on 
winecfg setting just like other dll? Is it reliable that these dll mixed 
togther? For example, the builtin gdiplus depend on and call ole dll, does the 
builtin gdiplus designed to work with both builtin and native ole dll?  Will 
there be any incompatibilities, like different memory allocator?

regards,
