have to expect the following table may be helpful. It was measured on
an Athlon/800MHz with "enough" memory:

COMMON PROBLEMS
working implementation has been available since GCC-2.95.3. GCC-3.0
and later have an even better, fully standard-conforming
implementation, by default. If you are stuck with GCC-2.95.2 or
-earliear and you cannot upgrade your compiler we recommend obtaining
+earlier and you cannot upgrade your compiler we recommend obtaining
