+# 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;
