Hi Support We are running GCC 4.1.1 on aix 5.3.0.0 on hardware Iserie v5r4. Question is what is the latest version that is supported on our platform ? Reason why we were looking at upgrading the version; It is giving hard time compiling any thing that includes iconv header Thanks Zhaleh Malek zmalek@missystems.com (615) 248-0079
