# for tests, allowing the test suite's main() to be used instead. This is a simple workaround
# to avoid having to refactor compiler.c. If compiler.c is refactored in the future to separate
# test helper functions from main(), this approach should be updated to link test_program() and
# run_program() from a separate object file.
