Hi, I have problem using the `swprintf` C standard library function with TCC on the Windows operating system. For example, `test.c`.

```
#include <wchar.h>
int main(void)
{
int r;
wchar_t buf[32];
r = swprintf(&buf[0], 32, L"%d\n", 42);
return r;
}
```

Command line: `tcc test.c`.
Output: `test.c:6: warning: assignment makes pointer from integer without a cast`.
When running the compiled program, it crashes.

The problem is taht according the C standard the `swprintf` function has the following signature
`int swprintf(wchar_t * restrict s, size_t n, const wchar_t * restrict format, ...);`, but the TCC
compiler think that the signature is `_CRTIMP int __cdecl swprintf(wchar_t*, const wchar_t*, ...);`.
So, there is mismatch and the compiled program crashes at run time.
