I'm not sure. It's possible that snapshot builds do not precompile
headers when installed (my 4.3 20070105 snapshot install doesn't have
them either).

They are not redundant: one is for C++03, the other is C++03 plus TR1
which is substantially different (includes many extensions defined
outside of the current ISO C++ standard).

I have to say, /usr/include never seemed like the best place for a
large binary file to me either. There may be a specific reason it's
done that way but I don't know it.
