I added the required header file (string.h) and only the warnings remain.

Not really :) Part of the problem may be with using GCC-4.3. I don't believe
that its fully supported by Boost.Config. As you can see 4.3 starts
deprecating the old hash_* headers, and the BGL uses these in a number of
places - or pulls them through some other header. It's a non-trivial job to
fix this. Any chance you'd be interested in downgrading your compiler :)
4.2.x seems to works nicely.

You should file a ticket over at svn.boost.org with exactly this
information, and I'll try to take a look at it sometime this week.
