I didn't see that. But wouldn't it make sense for you to just distribute 
everything with units already inside a directory called "mcs"?

Not. unit_test_4.cpp and unit_test_5.cpp have the same dependency.

Other observations:
1) unit_test_1.cpp depends on the boost.regex library. (Some of us have 
never built the boost.regex library. My solution is just to skip 
unit_test_1.cpp for now.)

2) The unit tests appear to build using gcc 3.4.4, but not with VC8.0. I 
get the following:
