I've just tried several test cases, and all worked! Great job!

Only used the Filesystem Library path_test and the vc7 toolset due to time
pressure. Note that path_test depends on the Filesystem Library build,
which has three input sources.

Here were the test cases:

1) No existing bin directories. Both build and test ran fine. As expected,
the residue files were a bit different: There was no path_test.success, and
path_test.test contained the word "passed" instead of the path to the .cpp
file. I've haven't looked yet to see if the lack of the path is a problem
for reporting, but hopefully the information is trivially available
somewhere else.

2) Missing source file for the library build. path_test.test was deleted,
so the reporting programs would know that failure occurred. The stdout
messages also indicated what had happened. Excellent!

3) Missing file restored. Worked fine; path_test.test was recreated, no
other files were touched.

4) Introduced error into one of the library files, causing a library build
compile to fail. path_test.test was deleted, so the reporting programs
would know that failure occurred. Excellent! This is the case that has
caused regression testing to report the wrong results in the past, so it
was good news to see it working correctly now. We probably should figure
out some other test cases just to be sure it is working for full coverage.

5) Fixed the error in the library file. The library build then worked, and
path_test.exe was relinked, without first recompiling path_test.obj. Test
was rerun. Exactly right behavior!

6) Ran bjam again, w/o changing any dependencies. As hoped, nothing was
out of date, so no actions taken.

Because of non-Boost time pressures, it will be the end of next week before
I can modify the status reporting programs to use "sane-testing".

Thanks for the improvements!
