 /*
 * XXX These routines belong in libm, but they must remain in libc for
 *     binary compat until we can bump libm's major version number.
+ *
+ * Note this only applies to the dynamic versions of libm and libc, so
+ * for the static and profiled versions we stub out the definitions.
+ * Otherwise you cannot link statically to libm and libc at the same
+ * time, when calling both functions.
