 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:

 When I tried to compile the kolmogorov max-flow example

  g++ -Wall -I /cs/phd/freiman/include/boost_1_36_0 kolmogorov-eg.cpp  -o

 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.
