For DLLs at least, you should be able to rename the .dll.so to a .dll
and stick it in the application's directory. I don't recall the last
time I tried this, but it certainly worked (I was using a hacked
ddraw.dll.so to get Diablo and Worms Armageddon playing nicely). I
assume you could do something similar for EXEs.

Is there some specific reason why you *need* WINEDLLPATH to override
standard built-ins? Is your APP.exe.so being called by some other
process that does not specify the full path, or something along those
lines?
