[ITP] pbzip2 (and what was the upshot on pbzip2/libbz2 incompatibility?)

[Peter Li]

This builds out of the box; I just pulled the packaging files from 
cygports (thanks!).  Think it's worth adding to main distro though.

It's in most distros:

     http://packages.debian.org/search?keywords=pbzip2
     http://www.freebsd.org/cgi/cvsweb.cgi/ports/archivers/pbzip2/

category: Archive
requires: libbz2_1 libgcc1 libstdc++6
sdesc: "Parallel BZIP2 de/compressor"
ldesc: "PBZIP2 is a parallel implementation of the bzip2 block-sorting
file compressor that uses pthreads and achieves near-linear speedup on
SMP machines. The output of this version is fully compatible with bzip2."


If I get a green light I'll go ahead and upload the package from my 
laptop when I get a moment.

Separately, I'm curious what the upshot was on this earlier discussion 
of pbzip2 incompatibilities:
     http://cygwin.com/ml/cygwin-apps/2011-03/msg00160.html

Did you ever figure out anything further on this?  Did you report any 
bugs to the pbzip2 project?  At my work we are using pbzip2 to compress 
critical data archives so I would definitely like to know if it is in 
fact incompatible in some subtle way.  If it's at all helpful, I have 
used Apache commons compress Java library to decompress these archives 
with no issues.

Thanks!
