 * including SIMDe to force the issue.
 *
 * Note that SLEEF does requires linking to libsleef.
 *
 * By default, SIMDe will use the 1 ULP functions, but if you use
 * SIMDE_ACCURACY_PREFERENCE of 0 we will use up to 4 ULP.  This is
 * only the case for the simde_math_* functions; for code in other
 * SIMDe headers which calls SLEEF directly we may use functions with
 * greater error if the API we're implementing is less precise (for
 * example, SVML guarantees 4 ULP, so we will generally use the 3.5
 * ULP functions from SLEEF). */
