<br>
Thanks Reid.<br>
I tried it before and it actually works in this simple case.<br>
<br>
The problem is that I have I big project with about 10000 files which<br>
is portable and which compiles fine on many platforms<br>
(win,linux,bsd,osx,android) with many compilers.<br>
<br>
Before -fms-extensions I had a few errors in only one file<br>
(which i can solve with a few #ifdef tricks).<br>
<br>
After I put globaly - CFLAGS +=-fms-extensions in my make file , I get<br>
houndreds of errors in connection with intrinsics.<br>
Like :<br>
../intrin-impl.h:960:10: error: definition of builtin function<br>
'_InterlockedExchangeAdd'<br>
__LONG32 _InterlockedExchangeAdd(__LONG32 volatile *Addend, __LONG32 Value)<br>
{<br>
<br>
...<br>
<br>
Of course I can make bigger changes in my build system or in my header<br>
files.<br>
But I think that main idea is that we will have on windows two clang<br>
compilers.<br>
One msvc compatible (name ,abi, parameters ...) which will be replacement<br>
for msvc compiler and<br>
other mingw (gcc) compatible.<br>
<br>
There are thousands of prejects which compile fine with gcc (mingw).<br>
It would be a nice if they compile out of a box with clang (with maybe some<br>
additional attribute).<br>
<br>
