No, by a script that Cygwin would have to create and that Emacs would call.  We 
already have scripts that do system-wide rebasing (and that are run 
automatically, without user intervention).  The question would be how to extend 
this to per-user rebasing.  Achim and I have just begun discussing this on the 
Cygwin mailing lists (currently the cygwin-apps list).  I think it's doable with 
some effort.

In the meantime, is it OK if I install my patch to enable building with native 
compilation?  That would simplify experimentation.
