Yes, but now I got this:

c++ -o dolfin\main\MPI.o -c -Wall -pipe -ansi -Werror -DDEBUG -g -DNDEBUG
-O2 -DPACKAGE_VERSION=\"0.8.1\" -I. -IC:\johannr\jhbuildbot\fenics\include
-IC:\local\src\boost_1_35_0 -IC:\local\include dolfin\main\MPI.cpp
scons: building terminated because of errors.
dolfin\main\MPI.cpp: In static member function 'static void
dolfin::MPI::gather(std::vector<unsigned int, std::allocator<unsigned int>
>&)':
dolfin\main\MPI.cpp:156: error: return-statement with a value, in function
returning 'void'
scons: *** [dolfin\main\MPI.o] Error 1
