graphml_test broken

[Dave Abrahams]

Problem 1: the test can't work unless bjam is run from the test's directory. The minimal fix:

graphml_test.cpp

 test-suite graph_test : 

However note that the original code actually yields an XML parse error rather than something that indicates the real problem. I suggest setting the bit on the ifstream that tells it to throw on failure.

Problem 2: The test still doesn't work.
