A Simple Testing Library for C

To prepare for a recent post graduate computer science class, I wrote a small library in C which aids in the creation of lightweight, unit-test-like programs. The code can be found here, and using it looks a bit like this:
#include"asserts.h"

int main(void)
{
c7e3_assert(1 == 1, "1 should equal 1");
c7e3_assert(2 == 2, "2 should equal 2");
c7e3_report();
return 0;
}
The design follows the KISS principle and I think it is a nice fit to the simplicity of C. While there is not much to it, I wrote numerous tests using it over the past couple of months and all of that testing certainly paid off.
