# SYNOPSIS
#
# AX_CXX_HAVE_LONG_LONG_FOR_IOSTREAM
#
# DESCRIPTION
#
# 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;
