This is only a very superficial comparison.  I compared the current
version (git clone git://git.sv.gnu.org/emacs.git) with the official
21.4 (i.e. 21.4a).

In x_calc_absolute_position the flag is 0x13 in place of 0x3. (If the
flag is set there manually, emacs behaves correctly).  I traced it
backwards towards x_set_offset. Here the change_gravity condition is
executed in the current emacs, but not in 21.4.  I simply redid
the comparison below.  This works now under the following

qvwm 1.1.12 (Senzoku) [built into IGEL-XTerms]
KDE 2.1.1

However, at startup my geometries Emacs.geometry: 101x39+-6+0 are
still ignored, but this has been the case since some time...
(the last time it worked is 20.7).
