It depends on whether you're talking about MinGW or Cygwin.  For MinGW
then you'll need to first install the pthreads-win32 library before
building gfortran/gcc, and possibly forcing the --enable-threads=posix
option since the MinGW default is --enable-threads=win32.  Since Cygwin
provides the pthreads API you don't need an external library there and
it should work OOTB.
