Other than the ones I got because as(1) from cctools can't grok CFI pseudo-ops (and probably never will because of Clang), I don't know of any symbol problems building Wine with Clang on Mac OS. Might have something to do with my system version (I'm still on 10.6, and I probably won't move until I find some way to run -arch ppc apps since Apple gutted Rosetta from 10.7...)

That's fixed in LLVM/Clang trunk. (I know, because I fixed it myself. A while ago, actually; I'm surprised Xcode doesn't have it yet.) Maybe the next version of Xcode will pick up the fix. Someone should really prod Apple about this :).

I suspect that's because Clang and newer GCC are smarter about identical typedefs. The ObjC BOOL vs. Wine BOOL issue wasn't about identical typedefs, because an ObjC BOOL is a "signed char" while a Wine BOOL is an "int". But a Mach cpu_type_t is an "integer_t"... which, ultimately, is a plain "int", the same as Wine's cpu_type_t.

Yeah, I'm not sure anyone really cares about the dead Apple GCC branch anymore... except AJ, but that's because his old Mac mini is stuck on 10.5, where we don't even have that problem. So long as Wine compiles with Apple GCC 4.x on Leopard, he'll be happy :).
