Thank you for the reply.
Yes, I needed to remove them in order to compile.

Ok thanks I was just thinking how to speedup the "code generation" phase
(after compiling and linking) in Visual Studio which takes about 5
minutes. Compiling is quite fast because I'm using dolfin as a static
library, but then the code generation is bloody slow (the full dolfin .lib
was about 120 mb which became 90mb after some "cutting", but it seems that
the rest is sort of linked together). I've been told that boost could be a
cause, so I just considered to experiment.
