There were two changes to configure[.in] between those dates:

revision 1.120
date: 2004/01/09 19:57:05;  author: glynn;  state: Exp;  lines: +3 -4
Don't generate makefiles in configure script
Only (re)build makefiles when necessary
----------------------------
revision 1.119
date: 2004/01/05 10:26:25;  author: paul;  state: Exp;  lines: +46 -5
(1) Experimental shared libary support (--enable-gmake=no --enable-shared=yes)
(2) --with-gdal is now the default
(3) startup script now called grass53 (NAME_VER=53)
(4) Set LD_LIBRARY_PATH properly in Init.sh

However, neither of these directly touched the Tcl/Tk checks.

Look for the corresponding error messages in config.log.

Which window manager are you using? twm doesn't put a "close" button
in the title bar; you have to select "Kill" from the root menu then
click on a window. This probably won't work with a rootless X server.

This suggests that GS_get_zrange_nz() is returning garbage, possibly
because it can't find a surface.

It could be related to the X server, possibly to its GLX support. Can
you run the "glxinfo" and "glxgears" programs?
