less (version 358) was downloaded from
[http://www.greenwoodsoftware.com/less/less358w.zip], they say it was
compiled with MSVC5.0
hello.exe is a standard C 4-liner:
  #include <stdlib.h>
  #include <stdio.h>

  int main()
  {
      printf("hello world\n");
      return EXIT_SUCCESS;
  }
and I have compiled it with Borland C++ 5.5.1.

I see the same with ls|more - it works under cmd, but under bash more
does not see any input.
