--- Comment #6 from Henri Verbeet hverbeet@gmail.com 2013-02-15 22:18:56 CST --- For what it's worth, I don't think it really makes sense to prefer Clang if it's installed just because OS X comes with a questionable build environment by default. (And for what it's worth, you can install e.g. proper gcc 4.7 even on OS X, either through something like Fink or MacPorts, or by just building it yourself.) I imagine the proper way to fix this is for winebuild to just respect the CCAS and CCASFLAGS environment variables (and similarly LD, LDFLAGS, etc.) when present, unless overridden by command line options, and just fallback to the system default otherwise. Or perhaps make configure pass appropriate command line options, if we don't want to look at the environment in winebuild.
