title: c++0x library availability in any compiler?
body: <p>The standard will doubtless take years to put in place, which stinks because it looks great.  But I was reading it, and at least the library additions (hash maps in particular) would be really useful right away.  I noticed in the g++ docs that I can get 4.3 or better and use a flag to request the new features, whatever exists, but I was wondering if there is any way to just get the library.  And the fact that lots of the best boost stuff is now built in is really great, finally a decent random number facility built in!</p>
  
  <p>So, are there any compilers which I can use right now which have a reasonably complete library in place, even if it can't use some of the cool new language features like auto?</p>
