First off, I'm not sure it's part of Cygwin yet.  Download the setup.exe
from http://www.cygwin.org and look through the list.  I didn't see it
as a separate package in the file list, but it could (and should) be a
standard utility now given POSIX/SUS standardization.  Then again,
Jorg's star has typically been far more POSIX/SUS compatible than GNU
(and its tar) anyway.

Secondly, you have to consider the "value" of a Cygwin "pax" versus a
true Windows 2000/XP "pax."  The former will use POSIX paths and values
for USTAR (pax) extended attributes, and will not tie into the Windows
extended attributes that 2000's "pax" could store.  Although I never did
any major, formal testing, I wanted to say that 2000 Pro's "pax" could
store some NTFS meta-data, but don't quote me.

I really need to do a study of how "Windows native" the "pax" utility is
in different programs.  It _would_ be nice if it could use the "pax" EAs
to store NTFS/Windows-only stuff.  "pax" is merely an extensible USTAR
format, so I don't see why not at least basic SID info can't be stored.

Although that _could_ be why Microsoft removed it in XP/2003, because it
wasn't working well.  Hence they UNIX-only "pax" in the Interix
component of more recent SFU (it used to be MKS' toolkit in earlier
versions).

It is mathematically impossible for someone who makes more than you
to be anything but richer than you.  Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them).  Linear algebra, let alone differential calculus or even ele-
mentary concepts of limits, is mutually exclusive with US journalism.
So forget even attempting to explain how tax cuts work.  ;->
