Hmm. Adding more debug output to preopen.c:vm_open  ...

Err...why is it looking for a module named "/usr/bin/last"? Is it
somehow using a $PATH search, and matching "last" to
"/usr/bin/last.exe"?  cygwin's dlopen does do some funky things with
$PATH, because that's how windows looks for DLLs -- but we're in
preopen, here...

Peter, can you try the attached patch "on top of" your mods, on some
platform OTHER than cygwin, and tell me what output you get?
