It's a problem of cmd.exe which doesn't pass the standard input
handle when opening an associated file.

c:\home\nobu> type foo.c
#include <windows.h>
#include <stdio.h>

int main()
{
    printf("stdin=%x\n", GetStdHandle(STD_INPUT_HANDLE));
    return 0;
}
c:\home\nobu> $ gcc -mno-cygwin foo.c -o foo.exe
c:\home\nobu> ftype foo=c:\home\nobu\foo.exe
foo=c:\home\nobu\foo.exe
c:\home\nobu> assoc .foo=foo
.foo=foo
c:\home\nobu> echo. > 1.foo
c:\home\nobu> 1.foo
stdin=0
c:\home\nobu> foo
stdin=150
