OK, I understand: misexec is in fact a shell script that calls the wine executable. So,
It's not a shell script but a Windows executable that exists in both 32-bit and 64-bit flavors in a Wow64 build.
I believe this problem occurs when someone starts a 32-bit winelib program on a 64-bit prefix from the command line or a script, so maybe we should just print a helpful warning message.
