You can't just rename the file to .so.  That's because it's a Windows
file and thus has PE headers, where .so files has ELF headers.

Wine should fallback to loading the native .acm version if the .so is not there.
Since Wine actually finds the .acm.so version, I imagine the acm is
being loaded through LoadLibrary or some such DLL loading function.

So maybe someone just forgot to make Wine check for native DLL files
named .acm in the DLL loading code?

Just a guess.
