Description
gcc version and system: g++ (Debian 4.3.1-9) 4.3.1
I tried to compile the graph example (boost/libs/graph/example/graph.cpp) using the following command: g++ -Wall -I /cs/phd/freiman/include/boost_1_36_0 graph.cpp -o graph
and got the following message about deprecated headers:
In file included from /usr/include/c++/4.3/backward/hash_set:64,
from
/cs/phd/freiman/include/boost_1_36_0/boost/graph/adjacency_list.hpp:22,
from graph.cpp:15:

Please use a non-deprecated interface with equivalent functionality instead. For a listing of replacement headers and interfaces, consult the file backward_warning.h. To disable this warning use -Wno-deprecated.
The running of this file was o.k.
When I tried to compile the kolmogorov max-flow example (boost/libs/graph/example/kolmogorov-eg.cpp) using the following command:

kolmogorov-eg

which has error due to the strcmp function in line 140 in the file: read_dimacs.hpp I added the required header file (string.h) and only the warnings remain.
When I tried to run this example using the following command:
kolmogorov-eg < max_flow.dat
I got a segmentation fault:
I tried to understand where the seg. fault came from using valgrind and it runs without seg. fault but with many "invalid read" errors, that seems to come from the file read_dimacs.hpp, line 118
Using the same code with WinXP and visual studio 2003, yields no problems.

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.

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