1. After applying the patch to GCC 5.2.0, the build fails (I do not see
PTW32_VERSION defined):

2. What is the appropriate test to verify the correctness of the order imposed?

3. My procedure is the following: I build GCC with Win32 threads, use it to
build the w32-pthreads library, and only then I build the compiler which uses
POSIX threads. Is there a better or simpler way? Building libgcc requires
pthreads, w32-pthreads compiled with gcc require libgcc. This looks like a
circular dependence.
