Hmm.  Confirmed, thanks.  I don't know what went wrong there; all of 
the binary packages do appear to be appropriately compressed, in the 
"dist" staging directory whence I uploaded them:

  $ file dist/*.xz
  dist/pthreads-GCE-w32-2.10-mingw32-pre-20160821-1-dev.tar.xz:   XZ compressed data
  dist/pthreads-GCE-w32-2.10-mingw32-pre-20160821-1-dll-3.tar.xz: XZ compressed data
  dist/pthreads-GC-w32-2.10-mingw32-pre-20160821-1-dev.tar.xz:    XZ compressed data
  dist/pthreads-GC-w32-2.10-mingw32-pre-20160821-1-dll-3.tar.xz:  XZ compressed data
  dist/pthreads-w32-2.10-mingw32-pre-20160821-1-doc.tar.xz:       XZ compressed data
  dist/pthreads-w32-2.10-mingw32-pre-20160821-1-lic.tar.xz:       XZ compressed data
  dist/pthreads-w32-2.10-mingw32-pre-20160821-1-src.tar.xz:       POSIX tar archive (GNU)

which comes directly from upstream; it is NOT build ready.

Please read the notes, at the foot of the FRS download page:
https://sourceforge.net/projects/mingw/files/MinGW/Base/pthreads-w32/pthreads-w32-2.10-pre-20160821-1/

The README source file for that is also present on the download page; 
it should have been included in the source tarball, but it appears to 
have been omitted.  I'll remedy that, together with the compression 
issue, and upload a fresh copy.

Additionally, you may note the availability of a pkgspec file, within 
the source tarball; this supports building with mingw-pkg[1]:

  $ pwd
  /home/keith/src/pthreads-win32-2.10

  $ mkdir -p build && cd build
  $ mingw-pkg --srcdir=.. patch configure compile
  $ make prefix=`pwd`/staged install

WJFFM, delivering:

  $ ls -R staged/
  staged/:
  bin  include  lib

  staged/bin:
  pthreadGC-3.dll  pthreadGCE-3.dll

  staged/include:
  pthread.h  ptw32_errno.h  _ptw32.h  sched.h  semaphore.h

  staged/lib:
  libpthread.a      libpthreadGC-3.a      libpthreadGCE-3.a
  libpthread.dll.a  libpthreadGC-3.dll.a  libpthreadGCE-3.dll.a

[1]: If you don't have the latest version of mingw-pkg, with support 
for the --srcdir option, you can substitute SRCDIR=..; (the advantage 
of the option is that it makes the SRCDIR=.. assignment persistent, so 
you don't need to specify it every time you run mingw-pkg in a given 
build directory).

Keith.
