I don't sure that it shouldn't be needed. IMHO, it depends on implementation.
BTW, it works well on my installation: NT SP4, cygwin-20.1, coolview dll, no binary mounts, CYGWIN=binmode ... . Here is the respective chunk of source:

...
 dup2(fh1, 0);
 fseek( stdin, 0L, SEEK_SET );
 gets( fh1_IN );
...

This really works.

Wishes,

Michael
