No it doesn't.  At least, not in recent versions.
The following produces a warning only if I leave
the initial #define.

#define WARNINGS

#ifndef WARNINGS
#pragma warning(push)
#pragma warning(disable:4244)
#endif

template<class T>
char f(T t) { return t; }

#ifndef WARNINGS
#pragma warning(pop)
#endif

int main() {
    f(1);
}

In Christ,
