# This test depends entirely on the builtin rules and the existence of a C compiler.

# Tests several things about C compilation:
# 1) Correctly scanning command lines for include files.
# 2) Correctly calculating checksums so if files change we do not
# rebuild, but we always rebuild when necessary.
# 3) Tests the builtin rules.
#
# Replace the .c file multiple times and see which replacements trigger a
