I think that they did a cleanup of the libstdc++ headers to make them  
#include less.  I agree with you that the clang source should include  
hte headers it needs, not relying on an artifact of the libstdc++  
implementation.

I think your patch is right, thanks.

I applied both changes.  The only change I made was to turn <string.h>  
-> <cstring>, which is the functionally equivalent but more C++'y  
version of the header.
