Hi,

I believe the issue behind this is that the header guards for the following 2 files have the SAME header guard value of BOOST_FUSION_CATEGORY_OF_IMPL_09272006_0726.

boost/fusion/adapted/boost_tuple/detail/category_of_impl.hpp
boost/fusion/adapted/std_tuple/detail/category_of_impl.hpp

Amazing! I had this hunch, but on looking at the header guards, I concluded they looked like they are automatically generated :|

On that ground I dismissed the possibility of a collision... How did you 'make up' a new 'unique' header guard name?

Thanks!

The tail end of the header guard appears to be a datetime string, so I changed that to today's date. I imagined that if I was wrong with that assumption, that Joel would have used a different one.
