It would appear that there's something wrong with this macro. I've looked at it and I'm not sure how it happens...

What was the problem with static variables that necessitates a BOOST_UNITS_STATIC_CONSTANT?
A static variable will be different in every translation unit. That can cause a technical ODR violation.
I'm using the mcs units from the vault, has this problem been fixed or even noticed before? Is there a report of changes to mcs that I can view?
It hasn't been noticed before. I'm pretty sure it's a compiler bug. I'll try to fix it today. You can view the current version at http://svn.boost.org/trac/boost/browser/sandbox/units or svn checkout http://svn.boost.org/svn/boost/sandbox/units In Christ, Steven Watanabe
