Apparently I should consult the manual more often, it seems that the use of 
inline math functions can be suppressed by defining __NO_MATH_INLINES, are 
you able to try building with this define set to see if it helps, sorry but 
I'm unable to reproduce the issue here :-(

To build Boost.Math with the define set try:

bjam release --with-library=math define=__NO_MATH_INLINES

Thanks, John.
