If llvm is supposed to be a replacement/alternative to gcc it should just work.

I don't see where that's claimed, and I still think this is a valid bug.

'Attempts to', not 'is'. Regardless, wine is pretty portable, and strives to be
so. Porting to lllvm seems reasonable. Confirming.

When using the even more experimental clang C frontend (from llvm 2.6), 
errors are related to extern inline 

- when some asm() create a symbols already defined as a extern inline, the
assembler found two definitions;

- when object files are linked together, ld report those extern inline symbols
as multiple defined.


IMHO, wine should not rely on "extern inline" asis since it seems to be GCC
specific behavor which is reported incompatible with C99.

All the extern inline asm functions should be inside a #ifdef __GNUC__, if some
aren't they should be fixed. But if llvm defines __GNUC__ then it better be
compatible.

I'm having the same problem regarding asm construct conflicting with extern
inline symbols when building with CFLAGS="--std=c99".

Please file a separate bug for that, and attach a log of the errors you get.

So, now that we build with -std=gnu89, can this bug can be closed?
Or should we first adjust configure.ac to add that option if we notice
llvm being used?

Wine compiles fine now with simply:
$ export CC=clang
$ ./configure

however, it crashes on run for me (with -O2). I'll attach a backtrace.

Compiling and running are two different things, I think.  Sounds like this bug
can be closed, and someone should open a new one for crashes in wine built with
llvm.

Actually, works fine if you do:
CC=clang CXX=clang CFLAGS="-std=gnu89 -g" ./configure

Is there a fix in Wine that made this bug disappear, or LLVM was fixed instead?
In the latter case this bug should be closed as invalid.

I think a combination of both. There are quite a few patches in wine for Clang
fixes (some warnings, some errors).
