// We need to preemptively include <stdlib.h> before anyone[1] has a chance
// to include <limits.h>. We do this to avoid a linux clang build error, in
// -ffreestanding mode on automation, which happens when limits.h defines
// MB_LEN_MAX to some value that is different from what stdlib.h expects. If
// we include stdlib.h before limits.h, then they don't get a chance to
// interact badly.
