This problem (and others) are fixed in the latest development version (the 
git repository).  I recommend that you install git under Cygwin and use that 
to download the latest code (per 
http://gnuradio.org/redmine/wiki/gnuradio/Download).

You could also start with the 3.2.2 tarball (is there a reason you are using 
3.1.3?) and add patches, but many of the quick patches (when done "right") 
are more than simple hand edits and require that you run ./bootstrap before 
they will take effect.  For example, you can fix the usleep problem above by 
adding "#include <unistd.h>" before the call to usleep in config.h, but that 
fix will go away the next time you run ./configure; patching config.h.in 
will fix that, but the right way is to patch config/gr_pwin32.m4 and rerun 
./bootstrap and ./configure.

In any case, you will need the following:

 * Before ./configure:

       export CXX="g++ -mthreads"
       export LDFLAGS="-L/usr/local/lib -lws2_32"

If you want to try patching problems in 3.2.2:

 *  If using Python 2.5, after running ./configure edit Makefile to add 
"-shrext .pyd" to PYTHON_LDFLAGS

 * In config.h and config.h.in, add "#include <unistd.h>" before the call 
to usleep

 * In gnuradio-core/src/lib/missing, edit Makefile to remove references to 
posix_memalign

 * In gnuradio-core/src/lib/io, remove references to gr_histo_sink in 
Makefile.* and io.i

 * use "--disable-gr-msdd6000" on ./configure

 * If building usrp code, add "#include <config.h>" near top of 
usrp/host/lib/db_wbxng.cc"

I hope this helps.  Eventually, this will all be documented in the wiki, but 
until then feel free to ask when you run into problems.
