Description

« Hide

The well-formed program below fails to compile with 4.1.2. According to c.math, p8, the C++ header <cstdlib> adds an overload of div(long, long) that returns ldiv_t to the C function div(int, int) that returns div_t. Looks like we're missing that overload.

$ cat t.cpp && make t
#include <cstdlib>

int main ()
{
std::ldiv_t x = std::div (1L, 1L);
}
