<pre>MSVC gives the same diagnostic as clang. InterlockedExchangePointer() is a
macro in both the Microsoft Windows 8 SDK and in mingw64, and MSVC errors on
your example:
$ cat t.cpp
#include <windows.h>
int main() {
void *Dest;
void *Value = 0;
::InterlockedExchangePointer(&Dest, Value);
}
$ cl -c t.cpp -nologo
t.cpp
t.cpp(5) : error C2589: '(' : illegal token on right side of '::'
t.cpp(5) : error C2143: syntax error : missing ';' before '::'
Does this code work with mingw gcc? If so it seems like gcc is accepting
invalid code.</pre>
