bug#18215: 24.4.50; OSX 10.6.8; set-frame-size by pixelwise does not work following `make-fame`.

[martin rudalics <rudalics@gmx.at>]

 > As to a version of Emacs Trunk built this morning (August 7, 2014), it is no longer possible to set the frame size using pixelwise immediately following a call of `make-frame`, or when launching Emacs.

Can you tell me the date of the last build where this worked for you?

This should work, indeed.  Does it work correctly by evaluating just

(set-frame-size frame 1894 1054 t)

interactively?

I hope it continues to work for you on Windows.  Here setting the
initial size works as expected on Windows.  I don't have OSX to test it.
BTW, does "maximizing" your frame on OSX work?
