Ville brought a related case to my attention. With Glibc this compiles, and
finds libc's ::sqrt(double)
#include
int i = sqrt(0);
But on Solaris it doesn't even compile. Solaris libc provides all three

That's one possible reading, but I don't think the text you quote is precise
enough to say that reading is definitely correct or not. If that is what it
says, it might be unintentional. That paragraph is

The same problem exists for ::div in , and for ::abs in both
and . Calling ::abs(INT_MAX + 1LL) or abs(INT_MAX + 1LL) will overflow
