nonstandard extension used : float long
The default Microsoft extensions (/Ze) treat float long as double. ANSI compatibility (/Za) does not. Use double to maintain compatibility. The following sample generates C4216:
// C4216.cpp
// compile with: /W1
float long a; // C4216
// use the line below to resolve the warning
// double a;
int main() {
}
