Thanks, gcc/g++ can link no erros. but during a simple test,
Hello.cpp.exe can run as expected,
Hello.c.exe runing error with NULL pointer.

C:\>g++ -pipe -O2 -flto -o Hello.c.exe Hello.c

C:\>g++ -pipe -O2 -flto -o Hello.cpp.exe Hello.cpp

C:\>Hello.cpp.exe
Hello, Wolrd!

C:\>Hello.c.exe
<Pop up a NULL pointer dialog>

C:\>type Hello.cpp
#include <iostream>
int main()
{
    std::cout << "Hello, Wolrd!" << std::endl;
    return 0;
}

C:\>type Hello.c
#include <stdio.h>
int main()
{
    printf("Hello, World!\n");
    return 0;
}
