Hmm, and this worked correctly before? Are you running from the build directory?
I didn't realize this before, but any DYLD_ environment variables will be stripped when running from the build directory, because `./wine` or `./wine64` is a shell script, and system binaries (including `/bin/sh`) ignore/strip `DYLD_` env vars. But if you edit `wine`/`wine64` and set/export `DYLD_FALLBACK_LIBRARY_PATH` inside the script, it works.

Or, if you install Wine and then run it from there, `wine`/`wine64` is a binary, so `DYLD_FALLBACK_LIBRARY_PATH` works correctly.

I did some tests with the preloader and couldn't find any cases where it loses or mishandles the environment variables.
