I tried Wine with LLVM/Clang from svn recently, thought others may
like some of the results. I've also ran the static analyzer.

For reference, this is with:
wine-1.5.4-61-g8327e6f, plus the following patch:
diff --git a/include/windef.h b/include/windef.h
index 9cf98e7..e95388a 100644
--- a/include/windef.h
+++ b/include/windef.h
@@ -53,7 +53,7 @@ extern "C" {

see for more info. Wine was compiled using:
export CC="clang"
export CXX="$CC"
export CFLAGS="-g -O0 -std=gnu89 -Wno-conversion -Wno-invalid-source-encoding"

-Wno-invalid-source-encoding, because clang does not like our encoding
of strings in winex11/keyboard.c. There are 851 warnings of:
clang -c -I. -I. -I../../include -I../../include  -D__WINESRC__
-D_REENTRANT -fPIC -Wall -pipe -fno-strict-aliasing
-Wdeclaration-after-statement -Wempty-body -Wignored-qualifiers
-Wstrict-prototypes -Wtype-limits -Wwrite-strings
-fno-omit-frame-pointer -Wpointer-arith -I/usr/include/freetype2    -g
-O0 -std=gnu89 -Wno-conversion  -o keyboard.o keyboard.c
keyboard.c:267:17: warning: illegal character encoding in string
literal [-Winvalid-source-encoding]

The static analyzer found 2231 bugs (--disable-tests was used).
