In emacs 24.4 on Windows 7, runemacs is not able to get rid of the background console window

[jerry . asher]

On Windows 7, emacs 24.3, runemacs would start a gui emacs and I'd never see 
the extraneous background console window.

I just installed emacs 24.4 and it seems runemacs cannot get rid of the 
background console window.

Is anyone else seeing this, and is this a bug, or is there a way to suppress 
that background console window?

If it is a bug, where does it get reported?
