Right, and TR1 fails with:

compile-c-c++ 
..\..\..\bin.v2\libs\tr1\test\test_tr1_include.test\msvc-8.0\debug
\threading-multi\test_tr1_include.obj
test_tr1_include.cpp
..\..\..\boost/tr1/tuple.hpp(51) : fatal error C1083: Cannot open include 
file:
'boost/fusion/sequence/adapted/std_pair.hpp': No such file or directory

Which in turn causes most of Boost.Math to fail :-(

So... what do we do to fix this?  Obviously I could point to the new header 
(if you tell me where it is!) but then if we merged to the release branch 
without *first* merging fusion then it would break all over again - but on 
the release branch this time.

Double :-(

Ideas?

John.
