+/* musl defines SSIZE_MAX as LONG_MAX, so its type is always long. However, on 32-bit architectures, musl
+ * defines ssize_t as int. Strictly speaking, this is not a bug in musl. POSIX only requires SSIZE_MAX to
+ * evaluate to the maximum value representable by ssize_t; it does not require SSIZE_MAX itself to have type
+ * ssize_t. However, our code assumes that SSIZE_MAX has type ssize_t, as is the case with glibc. Cast the
+ * value explicitly so that SSIZE_MAX has type ssize_t. */
