[cfe-dev] clang doesn't compile simple code

[fprijate]

Hi

Here is sample output from compiling libpng which is part of our platform.

clang   -I. -I../../../../../../include -Wmissing-braces -Wreturn-type
-Wformat -Wimplicit-int
 -Wimplicit-function-declaration -O3  -DUNICODE
-IG:/HRB_SVN/SRC-GIT/src/3rd/zlib -DPNG_NO_STDIO

As you see intrin-impl.h is included from winnt.h 

#define __INTRINSIC_GROUP_WINNT /* only define the intrinsics in this file
*/
#include <psdk_inc/intrin-impl.h>

I also did a little hack changing psdk/intrin-impl to intrin.h in winnt.h
and here is result:

IMHO the simplest solution would be if clang/gcc preprocessor translates
_cdecl,_stdcall,... to
__attribute__((...)) .
