[boost] Sudden VC6 ICEs in BGL code

Recently (I haven't narrowed down when, yet)
libs/python/src/object/inheritance.cpp started to produce an INTERNAL
COMPILER ERROR on VC6.  This file almost exclusively uses the Boost
Graph Library; there's almost nothing specific to Boost.Python going
on there.  The ICE happens, it seems, because of the use of
breadth_first_search.

In an effort to see what was going on, I made the graph library's own
bfs.cpp test compile with BOOST_NO_PARTIAL_SPECIALIZATION; it works
on vc7, but (guess what?) ICEs on VC6.

Does anyone have a clue what's going on?
