That's hardly "best". We need to try again, and get GCC to listen. I don't care about mingw.org... we can do something vendor-specific for that. But I do care about having GCC do a fixincludes on our headers, that we then revert. That's just plain stupid. Who's the GCC maintainer that we need to hit over the head? ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
