Why does gnuemacs ignore my xmodmap changes?

[Jonas Jarnestrom]

This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

In GNU Emacs 20.6.1 (sparc-sun-solaris2.6, X toolkit)
 of Fri Mar  3 2000 on iris
configured using `configure  --with-gcc --with-pop --with-x-toolkit=lucid 
--bindir=/usr/local/bin --libexecdir=/usr/local/libexec'

The designer of the layout of the swedish Sun sparc keyboard should
have received a death sentence long ago for one of the most emacs hostile
layouts in the entire computer industry. The control key is situated,
now hold on to your armrests, in the lowest row on the left corner
(i.e below shift, to the left of the Alt key). This produces a very 
strained and
crooked working posture for the pinky if you use a one-hand grip to
produce the key bindings. After a prolonged period with this cramped
position I seem to have damaged my outer joint of the pinky.

Now to my real Q. To releave my pinky, I'd like to redefine the
keyboard, for example redefine Caps-lock to control, which can be
easily done with the xmodmap program. The sad thing is though that
gnuemacs seems to disregard the redefinitions I make.
Xemacs does at least complains explicitly on the redefinition, but
gnuEmacs is just mute and dumb.

Emacs normally permits the user to customize virtually every
conceivable aspect of the user interface, so why doesnt it permit
xmodmap redefinitions?
