have to expect the following table may be helpful. It was measured on

Problems with CLN
=================
-You should use at least CLN V1.0.2, since all earlier ones are
-somewhat buggy. Even V1.0.1 has a few problems and GiNaC will not
-support older versions. Please install it properly on your system
-before continuing with GiNaC.
+You should use at least CLN V1.0.3, since during the development of
+GiNaC various bugs have been discovered and fixed in earlier versions.
+To protect you, the "configure" script checks for a feature that was
+added in V1.0.3 so it won't continue with earlier versions anyhow.
+Please install CLN properly on your system before continuing with
+GiNaC.
