Hello,

I was compiling my program using latest U++ 11634, Mingw compiling for 32 bit platform.
I got the error:

C:\upp\uppsrc\Core\Mt.cpp (635): error: '_mm_pause' was not declared in this scope

located in Mt.cpp:

void SpinLock::Wait()
{
volatile int n = 0;
while(locked) {
#ifdef CPU_X86
_mm_pause(); //<< error
#endif
if(n++ > 500)
Sleep(0);
}
}

Any idea how to fix it?
Thanks,
Luigi
