Here are some instructions that *should* help:
1) Make a text file name '~/download/rope.diff' containing this:
--- toolchain_build_nios2/gcc-3.4.6/libstdc++-v3/include/ext/rope (original)
+++ toolchain_build_nios2/gcc-3.4.6/libstdc++-v3/include/ext/rope (working)
68,72d67
< /* Fix potential name clash */
<# ifdef index
<# undef index
<# endif
2) cd ~/buildroot
3) patch -p0 <~/download/rope.diff
4) make
Good luck, hopefully that should fix it.
Hippo, I'm a bit puzzled; wasn't this fixed already?
