Just a possibility. There is no specific example.
With this patch, the code below can work even if it is compiled as
cygwin binary.
#include <stdio.h>
#include <windows.h>
int main() {
COORD dest = {0, 0};
printf("\033[H\033[J\n");
DWORD n;
FillConsoleOutputCharacter (GetStdHandle(STD_OUTPUT_HANDLE),
'A', 80, dest, &n);
FillConsoleOutputAttribute (GetStdHandle(STD_OUTPUT_HANDLE),
FOREGROUND_RED, 80, dest, &n);
return 0;
}
