[Interest] mingw & Qt 5.2.0 problems (building for Android)

[Igor Mironchik]

I use the latest mingw but he can't compile next program:

#include <stdio.h>

int main( int argc, char ** argv )
{
     FILE * f = _popen( argv[ 1 ], "r" );
}

g++ -c -pipe -fno-keep-inline-dllexport -O2 -std=c++0x -fno-exceptions 
-frtti -Wall -Wextra main.cpp

main.cpp: In function 'int main(int, char**)':
main.cpp:6:39: error: '_popen' was not declared in this scope
      FILE * f = _popen( argv[ 1 ], "r" );
