--- Comment #5 from [e-mail] ---
copy native riched20, msvc*, d3dx9_* to application directory, run exe with env
WINEDLLOVERRIDES="xxx=n,b", wine2.x still load builtin version from
c:\windows\system32.

i traced native riched20 loading proccess by run a exe with WINEDLLOVERRIDES,
trace log call tell native riched20 found in app directory, But finally only
load builtin dll from c:\windows\system32.

my submitted problem may not be a bug, but it's a useful feature for some app
just need one or two native dll.
