AX_CXX_HAVE_LONG_LONG_FOR_IOSTREAM
Check if the compiler allow long long for [i|o]stream Seems that OpenBSD / gcc-3 don’t have it.
Eg:
#include <iostream>
#ifdef HAVE_SSTREAM
#include <strstream>
#else
#include <sstream>
#endif
#ifdef HAVE_NAMESPACES
using namespace std;
#endif
ostream str((streambuf *)0);
long long lo=1;
str <<
#ifdef HAVE_LONG_LONG_FOR_IOSTREAM
(long int)
#endif
lo;
