# -O3 because leaving this empty does not mean "use configure's default". ruby-build
# exports it as CFLAGS, which supersedes configure's own optflags, so an empty value builds
# at -O0 — measured 2-3x slower than the same source at -O3. (rbconfig still reports
# optflags: -O3 in that case, which is misleading; the timings are what to trust.)
#
# -fno-strict-overflow guards the fixnum overflow checks in these old sources, which assume
# signed overflow wraps — undefined behaviour that GCC exploits from -O2 up. On 1.8.7 its
# absence silently makes 2**64 evaluate to 0. Kept uniform across every definition here;
# it costs nothing measurable.
