Qt Creator can't deal with functions named 'emit'

If I create a trivial C++ program:

#include <iostream>
void emit(int val)
{
    std::cout << val << '\n';
}
int main(int argc, char** argv)
{
    emit(42);
    return 0;
}

This program compiles and runs just fine. However, when I open it in Qt Creator, I get a bunch of errors around the emit function.

If I change the name of the function to something else, the errors go away.

It seems like emit might mean something special in Qt-land and so even for non-Qt C++ projects Qt Creator treats it as a keyword.
