When compiling with clang-cl, the following code generates an error. This code
compiles without issue in cl.exe, and is adapted (simplified) from MS headers
(ntddk.h).

int main()
{
    __asm    {
    cmp cl, 32
    jc short done
    inc eax
done:
    inc eax
    }
}

sample.c:5:6: error: expected identifier
                jc short done
                   ^
1 error generated.

I have developed a 4 line patch that just ignores the word "short" in jump statements. I have a feeling this is not the right approach, and therefore will not submit the patch unless others feel it should be added.
