pax is in the package paxutils, which is not yet in cygwin.
http://directory.fsf.org/paxutils.html

Mark H. Colburn <markcol AT jhereg DOT com> created another `pax' program in 
1989. The 1.1 version was published in comp.sources.unix, volume 17. 
 From a 2.0 OS/2 port, Ian Stewartson made 2.1 and is working on version 
2.2. ftp://sunsite.unc.edu/pub/Linux/utils/compress/pax-2.1.tar.gz

However it's straightforward to build paxutils. (into /usr/local)

cd /usr/src
wget ftp://alpha.gnu.org/pub/gnu/paxutils/paxutils-2.4h.tar.gz
tar xfz paxutils-2.4h.tar.gz
cd paxutils-2.4h
./configure
make && make check
make install DESTDIR=/usr/src/paxutils-2.4h/.inst

several tar tests will fail:
44. ./t-create.m4:3     ok
45. ./t-create.m4:14    ignored near `t-create.m4:14'
46. ./t-create.m4:40    ok
47. ./t-create.m4:56    ok
48. ./t-create.m4:76    FAILED near `t-create.m4:120'
49. ./t-extract.m4:3    ok
50. ./t-extract.m4:17   ignored near `t-extract.m4:17'
51. ./t-extract.m4:37   ok
52. ./t-extract.m4:53   ok
53. ./t-extract.m4:68   ok
54. ./t-exclude.m4:3    ok
55. ./t-append.m4:3     ok
56. ./t-delete.m4:3     FAILED near `t-delete.m4:16'
57. ./t-delete.m4:20    ok
58. ./t-incremen.m4:3   FAILED near `t-incremen.m4:23'
59. ./t-incremen.m4:27  ok
60. ./t-gzip.m4:3       ok
61. ./t-volume.m4:3     ok
mv: cannot move `stderr2' to `stderr': Permission denied
...

Note that paxutils includes unstable versions of tar and cpio. That 
might be the explanation why.

I have another version from the MS resource kit:
$ pax --help
c:\WINNT\system32\pax.exe: illegal option---
Usage: c:\WINNT\system32\pax.exe -[cimopuvy] [-f archive] [-s replstr] 
[-t device] [pattern...]

Reference Help in the Windows Help file.
