This is not quite accurate.  DYLD_* variables are only stripped when exec-ing
protected binaries.  There is no general prohibition against them propagating
to child processes.  Unfortunately, the system-provided script interpreters,
such as /bin/sh, are protected binaries.  So, DYLD_* variables are stripped
when a shell script is started.

But, for example, if one had a wine script to wrap the launching of the wine
executable and that script itself were to set DYLD_* variables before running
the wineloader executable, those variables would be inherited by and affect the
operation of the wineloader process as desired.

I don't know exactly what Homebrew does for its Wine install or how it
currently tries to use DYLD_* variables.  Mechanisms are available to avoid
this problem, at least in theory.
