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
-a P-III/500MHz with "enough" memory:
+an Athlon/800MHz with "enough" memory:
step: | GCC optimization level: | comment:
| -O0 | -O1 | -O2 |
--------------+--------+--------+--------+-------------------------------
-make | ~4m | ~6m | ~10m | building shared and static lib
-make check | ~3m | ~3m | ~7m | mostly due to compilation
+make | ~4m | ~5m | ~6m | building shared and static lib

COMMON PROBLEMS
--------------+----------------------------------------------------------
< 5.14.39 | `VERBOTEN' by license (please bite your favorite lawyer)
< 5.14.39,40 | compiles but does not feel happy at all (inconsistent!)
- 5.14.41 | tested on egcs 1.1.1, gcc 2.95.2: only minor weirdnesses
+ 5.14.41 | tested on egcs 1.1.1, gcc 2.95.2: some weirdnesses
+ 5.14.44 | does not compile: G__cpp_ginaccint.C needs manual fixes
+ 5.14.45 | compiles fine, still some weirdnesses during execution
