I am working with Eric to clean up the Linux/mips configuration in gcc 3.x. I'd like to change WCHAR_TYPE from "long int" to "int". They are the same on Linux/mips. There won't be any run-time problems. I am wondering if there are any compatibility problems at the compile time at the source and binary level. For one thing, __WCHAR_TYPE__ will be changed from "long int" to "int". The only thing I can think of is the C++ libraries. But gcc 3.x doesn't work on Linux/mips. The one I am working on will be the first gcc 3.x for Linux/mips. So there shouldn't be any problems. Am I right? H.J.
