../../emacs/src/widget.c: In function ‘EmacsFrameQueryGeometry’:
../../emacs/src/widget.c:457:29: warning: ‘ok_height’ may be used uninitialized
in this function [-Wmaybe-uninitialized]
if ((mask & CWHeight) && (ok_height != request->height))
~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../../emacs/src/widget.c:455:18: warning: ‘ok_width’ may be used uninitialized
in this function [-Wmaybe-uninitialized]
result->width = ok_width;
~~~~~~~~~~~~~~^~~~~~~~~~
I checked that the warnings are legit. With
(setq frame-resize-pixelwise t)
ok_width is used in the `if'. Not ok_height, at least on my experiments,
but removing the warning would be nice.
Note that the warning for `ok_width' points to the assignment, but it is
used right before on the `if'.
