I rebuild all Boost libs from trunk.

(Side-Q: why does bjam --show-libraries list function_types as a library
to be built, when the built does nothing?)

Indeed, the "exception related" problem is gone.

I still need the 3 patches attached for a full build.

First patch is for Boost.Math ... there is no log1pl on this target.

The other 2 are for Boost.Filesystem .. again multiple definitions while 
linking.
