Just a stylistic thing, but since the only use of "wone" is in
the eq_p, it'd be simpler just to use "1". Also, the maximum
value is better calculated as "wi::max_value (prec, SIGNED)". So:
/* Compute the value of SSIZE_MAX, the largest positive value that
can be stored in ssize_t, the s

Bug 81908 is about a -Wstringop-overflow warning for a Fortran
test triggered by a recent VRP improvement. A simple test case
that approximates the warning is:
void f (char *d, const char *s, size_t n)
{
if (n > 0 && n <= SIZE_MAX / 2)
n = 0;
memcpy (d, s, n); // n in ~[1, S
