Your glibc and gtk version not old, the building environment seems
good, but here I don't have a OpenSUSE 10.3 x86_64, really no idea on
how to resolve that problem, maybe I have chance to install a OpenSUSE
10.3 x86_64 these days, the I will try that,

Today I tested these patches on another pristine debian-5.0 (lenny)
x86_64 system, it also performed well.
On systems I tested (glibc 2.6,2.7,2.8, gtk-2.12 or gtk-2.14), it may
report warnings from gtkitemfactory.h and ununsed variables from
images.c, but doesn't matter, after "scripts/kconfig/gconf
arch/x86/Kconfig" run, the gtk gconfig window will display, with
symbol's value quoted well,

The get_symbol_str function is totally moved from mconf.c, and kept
intact, to make it available not only used by menuconfig, but also can
be used by gconfig & xconfig & config,

Maybe you can try to "make gconfig" from a vanilla
linux-2.6.29-rc6-git5 kernel, without these kbuild patches, to check
if your system can configure kernel with gconfig?

Alternatively, you can use this to compile gconfig,

gcc -Wall -Wl,--as-needed -Wstrict-prototypes -O2 -fomit-frame-pointer
-D LKC_DIRECT_LINK `pkg-config --cflags gtk+-2.0 gmodule-2.0
libglade-2.0` -o scripts/kconfig/gconf scripts/kconfig/gconf.c
scripts/kconfig/kconfig_load.c scripts/kconfig/zconf.tab.c -lncurses
`pkg-config --libs gtk+-2.0 gmodule-2.0 libglade-2.0`

this will build a smaller scripts/kconfig/gconf, with less library
dependencies, or try "-O2" to "-O0", "-ggdb" to compute more debuging
information, thanks,

In the same time I found the scripts/kconfig/gconf building command
have superfluous paramters, such as "-lncurses", gconfig doesn't need
ncurses, I will post patches to reduce that later.
