I hope that you have considered the Gnulib documentation on this topic:

And what's the execution environment? Is it Windows or is it wine? wine is
not supported; I've had enough work making it work on Windows.

Also, are you configuring with --enable-threads=windows? If yes, then
it should work (on Windows). If not, then if the winpthreads library
is found, it will be used; but since this library is broken, some of the
tests will hang, crash, or fail. To avoid using this broken library,
add this macro invocation to your configure.ac:
  gl_AVOID_WINPTHREAD
