/* inih -- unit tests

This works simply by dumping a bunch of info to standard output, which is
redirected to an output file (baseline_*.txt) and checked into the Subversion
repository. This baseline file is the test output, so the idea is to check it
once, and if it changes -- look at the diff and see which tests failed.

See unittest.bat and unittest.sh for how to run this (with tcc and gcc,
respectively).
