2444	read_dimacs problem with gcc 4.3	freiman@…	Andrew Sutton	"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:

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."	Bugs	closed	Boost 1.38.0	graph	Boost 1.36.0	Problem	fixed
