Never mind.  I searched the archive and found the details in an earlier 
post of yours:

   https://sourceware.org/ml/cygwin-xfree/2011-08/msg00046.html

Here's what I found when I tried to reproduce the problem:

 >> (raise-frame f)

I agree that this doesn't work.  But there's a post by Oliver Schmidt 
(https://sourceware.org/ml/cygwin-xfree/2011-08/msg00047.html) 
purporting to have a fix for this.  There is later discussion in which 
Jon Turney had some questions about the patch, but I didn't read all of 
it.  Jon, was this ever resolved?

 >> (iconify-frame f)

This works.

 >> (decionify-frame f)

There's no such function in GNU emacs (even after correcting the obvious 
typo).

 >> (make-frame-visible f)

This seems to be working.  Maybe you're misunderstanding what "visible" 
means in this context (or maybe I am).  The frame is initially visible, 
even if other windows are hiding it, as evidenced by the fact that 
(frame-visible-p f) evaluates to something non-nil ('icon' if the frame 
is iconified, 't' otherwise).  If I now make it invisible by evaluating 
(make-frame-invisible f), both the frame and its icon disappear. 
There's no way to bring it to the front by using Alt-Tab.  The frame and 
icon reappear if I now evaluate (make-frame-visible f).

In summary, the only problem I see is with raise-frame, and maybe that 
one is fixable.  We'll have to wait to hear from Jon and/or Oliver.
