Comment:

 The threading detection doesn't yet work for gcc 4.7 with the mingw32
 target.

 mingw32 gcc defines (for some time already) __GLIBCXX__.
 Up to 4.6, it used to define _GLIBCXX_HAVE_GTHR_DEFAULT as well, that's
 why it worked up to 4.6.

 Now 4.7 no longer defines _GLIBCXX_HAVE_GTHR_DEFAULT, which prevents
 threading from compiling.
