gcc46-pr47430-workaround.patch

This patch shows a sample implementation of 4) which seems to work just fine. 
It should have no effect on what is actually provided by the headers, just make
sure stdc++.gch/* isn't used during stdtr1c++.gch etc. compilation.

BTW, it surprises me that for -std=c++0x extc++.h doesn't include
bits/stdc++.h, I can understand why it doesn't include tr1 stuff in that case,
but I'd expect the standard stuff to be included nevertheless.
