Subject: Functional tests for C library
MIME-Version: 1.0

While gearing up to make an addition to the C library, I became
concerned at the lack of test infrastructure for the project.  The build
system now integrates Check <http://check.sourceforge.net/>, a
lightweight testing framework for C, and there are a few tests to ensure
no serious regressions occur.  You can run the tests with “make check”.
