I run 32-bit, so I tested only that, but MINIMIZE in STYLE now works!
Hooray!  This is the first time that emacs has properly minimized on
startup and properly un-minimized when first clicked!

Yes, the first two geometry measures for emacs are indeed in terms of characters.

Here is output when I request 110x64+0+0 on my laptop

xwininfo: Window id: 0xe00054 "xemacs"

  Absolute upper-left X:  9
  Absolute upper-left Y:  38
  Relative upper-left X:  9
  Relative upper-left Y:  38
  Width: 1103
  Height: 983
  Depth: 24
  Visual: 0x21
  Visual Class: TrueColor
  Border width: 0
  Class: InputOutput
  Colormap: 0x20 (installed)
  Bit Gravity State: NorthWestGravity
  Window Gravity State: NorthWestGravity
  Backing Store State: NotUseful
  Save Under State: no

  Override Redirect State: no
  Corners:  +9+38  -808+38  -808-59  +9-59
  -geometry 108x64+9+38

This is from requesting 110x65+0+0:

xwininfo: Window id: 0xe00054 "xemacs"

  Absolute upper-left X:  9
  Absolute upper-left Y:  38
  Relative upper-left X:  9
  Relative upper-left Y:  38
  Width: 1103
  Height: 983
  Depth: 24
  Visual: 0x21
  Visual Class: TrueColor
  Border width: 0
  Class: InputOutput
  Colormap: 0x20 (installed)
  Bit Gravity State: NorthWestGravity
  Window Gravity State: NorthWestGravity
  Backing Store State: NotUseful
  Save Under State: no
  Map State: IsViewable
  Override Redirect State: no
  Corners:  +9+38  -808+38  -808-59  +9-59
  -geometry 108x64+9+38

And this from 110x66+0+0:

xwininfo: Window id: 0xe00054 "xemacs"

  Absolute upper-left X:  9
  Absolute upper-left Y:  38
  Relative upper-left X:  9
  Relative upper-left Y:  38
  Width: 1103
  Height: 983
  Depth: 24
  Visual: 0x21
  Visual Class: TrueColor
  Border width: 0
  Class: InputOutput
  Colormap: 0x20 (installed)
  Bit Gravity State: NorthWestGravity
  Window Gravity State: NorthWestGravity
  Backing Store State: NotUseful
  Save Under State: no
  Map State: IsViewable
  Override Redirect State: no
  Corners:  +9+38  -808+38  -808-59  +9-59
  -geometry 108x64+9+38

I verified that I was changing the right file by adjusting
the width to 80 instead of 110, and it changed.

If I take that 80x66+0+0 window and drag the bottom down to add
a line, we get this:

xwininfo: Window id: 0xe00054 "xemacs"

  Absolute upper-left X:  9
  Absolute upper-left Y:  38
  Relative upper-left X:  9
  Relative upper-left Y:  38
  Width: 803
  Height: 998
  Depth: 24
  Visual: 0x21
  Visual Class: TrueColor
  Border width: 0
  Class: InputOutput
  Colormap: 0x20 (installed)
  Bit Gravity State: NorthWestGravity
  Window Gravity State: NorthWestGravity
  Backing Store State: NotUseful
  Save Under State: no
  Map State: IsViewable
  Override Redirect State: no
  Corners:  +9+38  -1108+38  -1108-44  +9-44
  -geometry 78x65+9+38

(Curious that the 80 was not obeyed, huh?  There's plenty of
room in that dimension.)  The vertical dimension may get short-
changed because it pushes right up against the icon bar at the
bottom of the screen.  I guess emacs does its own mystical
adjustment of the parameters, given available font sizes, etc.
I don't think this is a Cygwin-X specific thing, but if you
have any additional thoughts, they're welcome!

Thanks, as always, for your work on X for cygwin!   Eliot
