Hello fellow DJGPP-ers,
I came across a weird problem with DJGPP (GCC 2.8.1). In the following
program gets() should wait for input, but it doesn't. What's wrong? The
strange thing is that if I insert a call to getch() between scanf() and
gets(), getch() waits for input, but gets() still does not. With Turbo
C++ 3.0 it works fine (i.e., gets() waits for input).

Thanks in advance,
Daniel

#include <stdio.h>

int main(void)
{
  int x;
  char string[10];

  scanf("%d", &x);

  fflush(stdin);
  gets(string);
  puts("hello");

  return 0;
}
