Boost C++ Libraries: Ticket #2444: read_dimacs problem with gcc 4.3

Simply #define BOOST_NO_HASH. This will disable hash_* support of the BGL and thus silence the warnings. I've done this here.

That would be nice if Boost.Config could detect this. Unfortunately, the new headers are only available with --std=cxx0x and this opens a new can of worms...

Solved only the first warning, and not the: "deprecated conversion from string constant to 'char*" in read_dimacs.hpp line 105. In addition the seg. fault from the kolmogorov-eg example was not solved by this.

(In [49554]) Added a compiler check to adjacency_list.hpp that checks for GCC >= 4.3 and defines BOOST_NO_HASH. Closes #2444.

milestone Boost 1.37.0 → Boost 1.38.0

Note that this fix (r49554) will break any code that uses hash* selectors under GCC >= 4.3 - which is probably the right thing to do since hash_* was deprecated in favor of the unordered* data structures in tr1/0x. See #2467 for more information.

Reverted previous compiler check (r49554). It's probably not a good idea to deprecate these. Will add documentation on how to get around warnings.
