2.20. What do I need for C++ development?
-{HJ,AJ} You need either egcs 1.0.2 or gcc-2.8.1 with libstdc++ 2.8.1 (or

+{HJ,AJ} You need either egcs 1.1 which comes directly with libstdc++ or
+gcc-2.8.1 together with libstdc++ 2.8.1.1. egcs 1.1 has the better C++
+support and works directly with glibc 2.1. If you use gcc-2.8.1 with
+libstdc++ 2.8.1.1, you need to modify libstdc++ a bit. A patch is available
+as:
+ ftp://alpha.gnu.org/gnu/libstdc++-2.8.1.1-glibc2.1-diff.gz

+{UD} But since in the case of a shared libstdc++ the version numbers should
