Builds with gcc 7.0 fail with:
../test-skeleton.c: In function ‘legacy_test_function’:
cc1: error: assuming signed overflow does not occur when \
assuming that (X - c) <= X is always true [-Werror=strict-overflow]
Ignoring this warning until the test or compiler is adjusted.
Disabled with -Wno-strict-overflow. Attempted -Wstrict-overflow=1,
but it still results in the same warning.
