thank you for sending in this report. It is a problem in the adapter
code in boost/icl/gregorian.hpp. For operators ++ and -- that are
implemented for gregorian::date the keyword 'inline' is missing :(
The same problem exitsts for boost/icl/ptime.

Either you provide the missing keyword yourself in your boost version
or you apply the patchfiles attached. I'll fix the issue in the boost
trunk.

Cheers,
Joachim
