Reini, this diff implies that the version of perlrebase I have is out of da=
te since it doesn't use peflags anywhere.  I also found an old post from ba=
ck in July where you stated that its "baseaddr=3D0x5400000" is missing a 0,=
 suggesting it is at least that old.
http://cygwin.com/ml/cygwin/2010-07/msg00146.html

Where do I get an updated perlrebase?  I've tried performing updates from t=
he latest released cygwin installer (no snapshots), but I still have what a=
ppears to be an outdated version.

Perhaps this is part of my current cpan/rebase hell....
