Why would we do that instead of patching the DLL?  That doesn't make
any sense.

Are you somehow not getting the fact that the DLL was going to be
changed despite the fact that I said I was going to do it?  This has
been done.  You don't need to do anything here.

Please drop this now.  It's clear that no one has any clever ideas about
how to make this work that doesn't involve patching every application
that uses errno.  So, this discussion should just die.
