I follow the steps in the thread http://www.myopenrouter.com/forum/thread/10208/Stil-Can-t-get-a-good-build-fo...
But I still got exactly the same problem with the thread opener. How should I figure this out?

I am compiling wgr614v8-v1.1.1_1.0.20. But I compiled toolchain first and met this problem. I am using FC10, linux kernel 2.6.18 & gcc version 4.1.2.
The README.txt in tools-src said:
To make the GNU toolchain
o cd to ../release/src/router
o make menuconfig
save defaults and return
o Get back to the tools-src directory and run
build_tools.sh

When I run make menuconfig in ../org/src/router
I got:
make -C config
make[1]: Entering directory `/home/bo/netgear/org/src/router/config'
gcc -I/usr/include/ncurses -DCURSES_LOC="" -I. -c mconf.c -o mconf.o
mconf.c:93: error: static declaration of ‘current_menu’ follows non-static declaration
lkc.h:59: error: previous declaration of ‘current_menu’ was here
make[1]: *** [mconf.o] Error 1
make[1]: Leaving directory `/home/bo/netgear/org/src/router/config'
make: *** [mconf] Error 2

And when I run ./build_tools.sh, the log ',xgcc-build.log' shows:
........
/home/bo/netgear/org/tools-src/gnu/gcc/gcc/read-rtl.c: In function ‘fatal_withile_and_line’:
/home/bo/netgear/org/tools-src/gnu/gcc/gcc/read-rtl.c:62: warning: traditional C rejects ISO C style function definitions

gmake[1]: Leaving directory `/home/bo/netgear/org/tools-src/obj/xgcc/gcc'

So I got exactly the same problem with hrlevy in the link above, but he didn't say whether he has figure it out.
