+The time the "make" step takes depends heavily on optimization levels.
+Large amounts of memory (>128MB) will be required by the compiler,
+also depending on optimization. To give you a rough idea of what you
+have to expect the following table may be helpful. It was measured on
+an Athlon/800MHz with "enough" memory:
+
+step: | GCC optimization level: | comment:
+ | -O0 | -O1 | -O2 |
+--------------+--------+--------+--------+-------------------------------
+make | ~4m | ~5m | ~6m | building shared and static lib
+make check | ~20m | ~11m | ~12m | largely due to compilation

+COMMON PROBLEMS
+===============
+
+Problems with CLN
+-----------------
+
+You should use at least CLN-1.1, since during the development of
+GiNaC various bugs have been discovered and fixed in earlier versions.
+Please install CLN properly on your system before continuing with
+GiNaC. When using GCC3 as compiler please use at least CLN-1.1.1
+since some parts of GiNaC won't build with CLN-1.1.
