First, as I'm sure others will point out, there was no such thing as GCC 2.96 from the GCC project. "gcc 2.96" most likely refers to the compiler released by Red Hat for its Red Hat Linux 7.x series as well as Advanced Server 2.1. The version of the C++ runtime included with those compilers did not initially support wide characters. Due to customer requests, Red Hat eventually enabled wide character support in the C++ runtime for Advanced Server 2.1. To ensure ABI compatibility with existing deployments wide character support was not enabled by default -- hence the introduction of the -wchar-stdc++ option. > I cannot find documentation > for this option in the online gcc manuals. -wchar-stdc++ was never an option in any version of GCC from the FSF. It is a Red Hat-ism for Advanced Server 2.1 developers that needed wide character support in the C++ environment. > It is unrecognized by gcc 3.2.3. What should be used in its place in 3.2.3? GCC 3.2's C++ runtime should automatically include wide character support. ie, there is no need for a special switch to enable/disable wide character support in modern versions of GCC. I hope this answers your questions, Jeff
