[boost] [graph] Max Flow Uninitialized Warning in adjacency_list.hpp

When I try to compile the Edmunds Karp Max Flow example (or any of the other
max-flow examples) I get a set of warnings as to m_source or m_target being
used uninitialized in adjacency_list.hpp. I'm using gcc 4.2.3. Is there a
way to get rid of this warning?

Code example:

Warning example (this is all one line):
/usr/include/boost/graph/detail/adjacency_list.hpp: In function ‘int
