C unit testing

I looked around at unit testing frameworks for C today. CppUnit caught my attention because it mentions being written by Michael Feathers. However, I'm working on code for someone who is not a fan of C++ so I decided it would be better to aim for a pure C solution. I'm trying out CuTest. It seems it will fulfill my needs. (Check sounded better to me and seems to have seen some love and care more recently, but the configure script failed to work on my computer, and I didn't want to devote much time to just getting the framework itself to compile.) CuTest seems all right so far. I wish the library functions made it bit easier to programmatically access the test results, however. For instance, I would like the program to exit with status 1 if any of the tests fail (or make some other externally obvious sign that doesn't require parsing the text output). (Would it be bad style to use exit status for this?)
