I am a new user of boost (in particular BGL). For my project, I am using the function of "prim_minimum_spanning_tree" to construct the minimum spanning tree.

That's really strange... I changed "int" to "float" and everything
works with GCC (I don't have MSVC to test with). You should also change
the "property
